These are so good I can't stand it!
1lb chicken breasts (I used boneless/skinless)
1 medium yellow onion
2 cloves garlic
1 green and 1 red bell pepper (or 2 of the same color

)
2 tablespoons lime juice
1/2 tsp each oregano, ground cumin, chili powder and ground black pepper.
Cut chicken into 1/2 wide strips. Peel onion and cut into 1/4 inch rings. Put the onion in the slow cooker. Peel garlic and mince well. Remove stems and seeds from bell peppers and cut into 1/4 inch wide strips.
Combine garlic, lime juice, and spices and add chicken. Toss well to coat. Pour chicken and juice mixture over the onion in the crock pot.
Cover and clook on low for 6-8 hours. About 30 minutes before serving, stir in peppers. Cover and continue cooking on low for 30 minutes.
Spoon into warm flour tortillas and top with your favorite toppings. I like sour cream and sharp cheddar cheese!
I hope you enjoy!
