IMPOSSIBLE MEXICAN PIE

This old recipe clipping appears to be from an old Bisquick advertisement. I found this in my late mother's shoe box of  recipes.

1 lb ground beef
1/2 cup chopped onion
1 envelope (1 1/4 oz) taco seasoning mix
1 can (4 oz) whole green chilies, drained, seeded, chopped
1 cup shredded Monterey Jack cheese
1 1/4 cups milk
3/4 cup baking mix
3 eggs
1/8 tsp hot sauce

Preheat oven to 400 degrees.

Lightly grease a 10-inch pie plate. Cook and stir ground beef and onion in 10-inch skillet until beef is brown; drain. Stir taco seasoning mix into the beef and spread mixture in bottom of pie plate. Sprinkle with the chilies and cheese. Beat remaining ingredients until smooth, 15 seconds in blender on high speed or one minute with a hand beater. Pour into pie plate. Bake until golden brown and knife inserted halfway between center and edge comes out clean, 25 to 30 minutes. Let stand 5 minutes before cutting. Garnish with peppers and shredded cheese if desired. Refrigerate any remaining pie. 6 to 8 servings.
