Preheat oven to 375 degrees F. In a large saucepan, combine 1/2 Velveeta cubes, milk (you may need to add another 1/2 cup milk so not too thick) and 1 can of cheddar cheese sauce, cook for 10 minutes. Mix together. Pour a small amount into a 9 x 13 inch baking dish.
Lay out tortillas. Put a scoop of cheese mixture, a spoonful of cheddar cheese, a few spoonfuls of green chili peppers, and a few Velveeta Cheese cubes, in each tortilla, roll them up. Place tortillas in baking dish and pour the remaining cheese mixture all over top. Top with enchilada sauce, shredded cheeses, and green onions.
