TO STORE: Refrigerate leftovers in an airtight storage container for up to 4 days.
TO REHEAT: Reheat gently in the microwave or in a non-stick skillet over medium-low heat.
TO FREEZE. Freeze leftovers in an airtight, freezer-safe storage container for up to 3 months. Let thaw overnight in the refrigerator before reheating.
SERVING IDEAS: Try this Italian sausage and peppers over rice or cauliflower rice, inside a toasted hoagie bun with a slice of provolone cheese (bonus points for warming it in the oven to melt the cheese), or with whole wheat pasta noodles and tomato pasta sauce. I also like to sauté the leftovers with spinach, then top them with a fried egg for a tasty brunch (or brinner!).
