I have not tried it with GF Bisquick; if anyone tries it that way, please share your results.
In medium bowl, mix:
1/2 c. Bisquick baking mix
1 c. milk
2 eggs
Pour over meat in pie plate.
Sprinkle with 1c shredded cheddar cheese
Optional: crumbled bacon, chives, sauteed mushrooms
Bake at 375 for 25 minutes or until knife comes out clean.
Serve with salsa or barbecue sauce.
