In a large skillet, cook the sausage until no longer pink; drain.
Place 4 tortillas in a greased 9-in. pie plate, overlapping and extending 1/2 in. beyond rim. Place remaining tortilla in the center. Layer with sausage, Monterey Jack and cheddar cheeses and chiles.
In a large bowl, combine the eggs, cream, cottage cheese and chili powder; slowly pour over chiles. Bake at 350° for 45 minutes or until a knife inserted in the center comes out clean. Sprinkle with cilantro. Cut into wedges.
