**For Beef Type: you can use lean ground beef or steak. Skirt steak is really nice to use as it can be cut into long thin pieces- like that of a fajita.
**Phase 3 modifications: Stir fry with additional vegetables such as bell pepper or zucchini. Cook Mongolian beef with sesame, chili, peanut, or coconut oil and use soy sauce to add additional flavor. Top with 1 tablespoon of crushed peanuts if desired.
