Crock Pot:
2 Frozen boneless-skinless chicken breasts
1 can diced tomatoes including the juice
1 package of taco seasoning
1 can black beans
1 onion diced

Other:
Whole-wheat tortillas
Shredded low-fat cheese
Cooked brown rice (optional)
lettuce (optional)

Place frozen chicken breasts in crockpot and cover with other ingredients already mixed together.  Cook on low for 7-8 hours.  After cooking, stir with wooden spoon until all the chicken shreds (it will fall apart easily). 

Use this to make burritos.  Heat whole grain tortillas, fill with meat and bean mixture, cheese, rice and lettuce.  You can also ditch the tortilla and put the chicken and bean mixture over lettuce for a lower carbohydrate option.

Fresh, frozen, or canned Green beans (1 cup per person)

This will be 1/3 to 1/2 of your plate.  Fresh and canned, rinse them off with cool water prior to cooking.  You can place them in a steamer to cook or you can put them in a pan with 1 Tbs of olive oil and put on a lid to help cook them through 7-10 minutes.
