Grocery Tips: Pre-chopped mixes of bell pepper, celery, and onion are sometimes available in the produce section. While a little more expensive, it can be a time-saver. Also, 1 bag of frozen peppers stir-fry mix and onions can be used instead of fresh bell peppers and onion.

Keep it Healthy: Salmon is just as healthy as tuna, plus sometimes on sale and cheaper. Substitute 1 (15 oz.) can of low sodium salmon for the tuna.

Get the Kids Involved: Kids can help crush the cereal. Just put in a sealed plastic bag and let them gently smash with a rolling pin or the back of a small pan. They can also sprinkle the cereal on top of the casserole.
