TweetI've had this recipe but yet to have make it yet, lol. I always seem to find recipes and then never get to them. But this sounded good:

Slow Cooker Spinach And Chicken
(Makes approximately 4 quarts)
Ingredients:

4 large chicken breasts
1 pound frozen spinach
1 (28 ounce) can diced tomatoes
1 (18 ounce) jar of your favorite clean marinara (or 18 ounce of homemade marinara)
Directions:

Place all ingredients in a 5 quart slow cooker and cook on low for 6-8 hours. It’s done when the chicken easily falls apart.
Note: Times will vary based on your slow cooker. All crock pots cook differently.
