Cook your chicken for salads, fajita's or casseroles ahead of time. When I purchase chicken in bulk packs, it gets cooked up in the oven in 2-3 dishes with different seasonings. Once cooled, I slice it up and freeze in freezer bags for future meals.
Salads are made into a meal by simply taking a pack of cooked chicken out and thaw in the microwave! Diced cooked chicken is great for casseroles or chicken salad sandwiches or pitas.
