I got this recipe out of a book I got from Christine (I think I still owe her $10 for it...need to ask about that). When she still lived in
1 lb ground beef (I use 90/10 ground sirloin, but use whatever your tastes/budget allows)
1 can chili beans (do not drain!)
5-6 slices Velveeta
Shredded cheddar cheese (if you're a cheese junkie like us)
Lettuce, etc. (as desired)
Brown your ground beef with the taco seasoning. If necessary, drain some of the fat and put beef back in pan.
Pour chili beans over taco meat and cook on low until beans are heated through. Top with Velveeta slices and stir until cheese melts.
Serve in tortillas with cheese and whatever other taco toppings you might like.
We had them with just the meat/bean filling and a sprinkle of cheddar. But you can top them however you like. And then have leftovers to do it all again in a couple of days.
