This has got to be one of the simplest ways to make this yummy dish! And it's virtually mess free! These rellenos can be fried in oil or baked in the oven, depending on how you like it. If you like Mexican but don't like spicy stuff, you might like this. The canned green chilies don't tend to be very hot. Also use mild to hot salsa, depending on your family's taste. Great served with traditional refried beans and rice.
