Place 2-4 chicken breasts in a small crock pot.
Pour Italian dressing (from a bottle, not the powder mix) over the chicken until it is covered.
Cook for 4 to 6 hours and shred.
Add 1 bottle of spaghetti sauce like Barilla’s Tomato and Basil spaghetti sauce. You may need to add more than one bottle if you used more than 2 chicken breasts. Serve over angel hair pasta (or any pasta you prefer).
