Cut along one side of each chili and open to lie flat. Coat a 13-in. x 9-in. baking dish with cooking spray. Layer half of the chilies, tortilla strips, mozzarella and cheddar cheeses in prepared dish. Repeat layers.
In a small bowl, beat the egg substitute, milk, garlic powder, cumin, pepper and salt. Pour over cheese. Sprinkle with paprika.
Bake, uncovered, at 350° for 40-45 minutes or until puffy and a knife inserted 2 in. from the edge of the pan comes out clean. Let stand for 10 minutes before cutting. Serve with salsa. Yield: 12 servings.
