To make it into real chili, you'll want a couple cups of leftover taco meat to start with.
Put the leftover leftover taco meat into the crockpot on high (or a regular pot on medium)
Add 2 cans of chili beans,tomato paste, tomato sauce, boullion, chili seasoning, water and rotel.
Heat on high in a crockpot for a couple hours, or about 15 - 20 minutes in a regular pot.
Meanwhile, cook a half a box of elbow macaroni (about 8 oz dry) and add to the chili pot.
* I like to add about a little bit of the starchy pasta water to help thicken up my chili a little bit.
** If you have any refried beans leftover from taco night, feel free to stir some of those in as well!! They're also a great thickener and make use of every last bit of leftovers in the fridge.
