Step 1

Slice the bell peppers and onions into 1/4-inch strips. Lay half of the onion and peppers in the bottom of a 4-quart or larger slow cooker.

Step 2

Place the chicken breasts on top of the onions and peppers and season lightly with salt and pepper. Sprinkle the basil and oregano over the chicken.

Step 3

Cover the chicken with the remaining peppers and onions, then pour the marinara sauce over top.

Step 4

Place the lid on the slow cooker and cook on high for four hours or low for eight hours. After cooking, remove the lid and use tongs to stir the mixture and shred the chicken. The chicken should be so tender that it falls apart when pinched with the tongs.

Step 5

Serve the saucy mixture over pasta, rice, polenta, or stuffed into a roll as a sandwich.
