Split whole chilies lengthwise; remove seeds and lay flat in a 13-by-9-inch
baking pan. Place tofu on paper towels and press gently to remove excess
moisture. Crumble tofu and blend half of it with the Cheddar cheese and
half of the tofu with the jack cheese. Top whole chilies with half of
Cheddar cheese mixture and half of the jack cheese mixture. Add a layer of
the diced chilies.
Repeat layers of cheeses and chilies. Beat eggs with milk and pour over
all. Spread with salsa. Bake in 350-degree oven for 45 minutes.
