There are so many things I love about today’s recipe.

  1. It’s made in the slow cooker
  2. It only uses a handful of simple ingredients
  3. It has easy gluten free and paleo options
  4. It’s perfect for everything from summer picnics to winter pastas to busy weeknights any time of the year. Put it in a wrap, sandwich, serve with roasted veggies, with salad, on salad, in a taco, with rice…. the options are endless!

In this recipe I used Muir Glen Organic Fire-Roasted Crushed Tomatoes (new to Canada!), chicken breasts, and a bit of pesto and salt to punch up the flavor — you really need nothing else! The flavor of these tomatoes is so intense and incredible. Muir Glen uses only the best, vine-ripened tomatoes and you can tell as soon as you crack the can. The smell is intoxicating!

I wanted to show them off in a recipe that didn’t require a lot of ingredients, so that the fire-roasted flavor wasn’t lost under a bunch of other things.

Also, with a toddler and a preschooler I just don’t have a lot of time or patience for recipes with 27 ingredients and 8 pots. Do you?

  • 4 chicken breasts
  • 28 oz can crushed Fire Roasted Tomatoes
  • 1 tablespoon basil pesto
  • 1/4 teaspoon salt
  • 1 cup shredded mozzarella cheese
  • fresh basil leaves and buns to serve as desired


  • Place chicken breasts in a 4-6 quart slow cooker. Add tomatoes, pesto and salt and stir until chicken is coated.
  • Cook on low for 4-6 hours. Shred chicken and serve on a bun with shredded cheese and fresh basil if desired.
  • This chicken is also great in wraps, on salads, over pasta, rice or potatoes — the options are endless!


*I cooked 3 chicken breasts in one 28oz can, and there was lots of sauce for serving over pasta or rice. You can easily cook up to 5 chicken breasts in one sauce recipe, but you won’t have as much leftover for serving, so it’s perfect for sandwiches.
*If you’re looking for a longer cooking time (say you work away from home all day), use frozen chicken breasts and cook for 6-8 hours on low.
*This recipe is gluten free, but be sure that you use gluten free rolls or serve or rice or potatoes instead.
*If seeking a paleo option, omit the pesto and add fresh basil and/or oregano to taste at the end of the cooking time. Leave off the shredded cheese and serve with roasted vegetables.
*Nutrition information is estimated and will vary depending on exact serving size, types and brands of products used.

    I made this wonderful chicken sandwich on a Friday night. I put everything into the crockpot went to my son’s high school football game. When I got back from the game cold and tired all I had to do was shred the chicken and eat. That was a lifesaver. Later on when my son got back with is friends they loved it. One teenager wanted to pay me to come to his house to make the chicken and even said it was better than “Popeye’s” chicken sandwich. (very high praise) LOL I will make this again and again.

    I did change one thing: We are not very fond of pesto in my family so I substituted garlic paste. Thank you for a wonderful sandwich that the whole team enjoyed.

      I’m so glad to hear that Colleen! I love my slow cooker in the fall and winter, too — it makes dinner time so much less stressful, especially when you’re out and about!

    You have to be super organized.. You also have to Get your baby sitter to take your kids far away so your sweet kiddo’s won’t embarrass you! 🙂

    If being in love with a sandwich is wrong, I don’t wanna be right. I don’t see how any summer BBQ could go wrong if this recipe is involved! Love it!!

  4. Brenda Witherspoon-Bedard says

    I really try to make as much food before hand as I can – that way I less stressed on the actual day 🙂


    I love freezing fruit and using it as ice cubes in my drinks. I think it is awesome and works so well!

    I like to make a baked salmon with rice. Very easy and can mostly be prepared ahead of time.

    In the summer I do a planked salmon. One tip is to make sure you soak your plank ahead of time. While entertaining, you don’t want a bonfire in your BBQ.

  7. Laura M says

    I love making salsa with fire roasted tomatoes. I use the slow cooker for pulled pork sandwiches served outside. I usually plug it in outside or in the garage or Florida room, summer or winter so I’m not sick of the smell by the time to eat.

  8. Heather says

    Best tip … Have the dishwasher empty before the party starts. I always have extra plates and utensils because I always seem to run out. And of course, try to prep as much as you can ahead of time so you can enjoy your guests !

  9. Bailey Dexter says

    When I’m feeding a crowd I always make sure there are a lot of salads, meat trays and veggie trays so if anyone gets hungry while the meat is still grilling they can just help themselves. It always works for us here and everyone is always happy, full and content!

    prepare as much food beforehand so you can sit and visit with your guests, instead of being stuck in the kitchen
