The amazing thing about this egg dish is that you can toss pretty much anything into it, and it works perfectly. Use a variety of leftover ground beef from tacos, chopped ham, or some already-cooked maple breakfast sausages. Delicious! You can also use steak, salmon, crab meat, deli meat, and even leftover chicken. Frittatas are incredibly versatile and can be altered in a million ways to suit your needs. Any option is amazing mixed in with the egg goodness.
