Add Fennel Seed, Garlic Powder, Crushed Red Chiles, Oregano, and Salt & Pepper to ground buffalo & mix VERY well. Make patties ¼ to 1/3 lb to the shape of the bread. Grill or pan fry patties to no more than medium, melt a slice of mozzarella cheese on each patty then put 1 whole or ½ half green chile on top of cheese. Put on warmed bun. Sauce can be put inside sandwich or in a small bowl for dipping. YUM!
