This is how my mom made enchiladas..
Lightly fry the tortilla, fill with taco meat, cheese and onions, roll it up. Place in a pan, thats been coated with a bit of spray oil, and a thin layer chili.
Repeat until pan is full or you run out of stuff... lay enchiladas side by side, then put chili on top of all of them... then top it off with more cheese..
Put in oven for 25-30 mins at 350-375
And eat em
