FAQ
Can I use frozen vegetables instead of fresh cooked ones?
Yes, thaw and drain frozen vegetables completely before mixing to prevent excess moisture from making the casserole watery.
What if I don't have colby-monterey jack cheese?
Any good melting cheese works well including cheddar, mozzarella, or a Mexican cheese blend for different flavor profiles.
How long will leftovers keep in the refrigerator?
Properly stored leftovers keep for 3-4 days refrigerated and reheat well in the microwave or low oven.
