Baked Quesadilla Squares

2 c Cheddar cheese; shredded
2 c Monterey jack cheese; shredded
2 c Diced green chilies (4 oz)-drained
2 c Milk
1 c Buttermilk baking mix
4 Eggs; beaten to blend
1/4 c Salsa Sour cream
Guacamole Additional salsa

Preheat oven to 425 degrees. Spray 9 x 13-inch glass baking dish with nonstick vegetable oil spray. Sprinkle cheeses in bottom. Top with chilies. Combine milk, baking mix, and eggs in large bowl and beat until smooth. Carefully pour over chilies. Top with 1/4 cup salsa. Bake until puffed and golden, 25 to 30 minutes. Cool 10 minutes. Cut into squares and serve. Pass sour cream, guacamole and additional salsa separately.

NOTE: I think 425 degrees might be too hot for this dish. I would start it at 375 and bake a little longer if necessary.
