Okay this is real simple. Chop all your fresh shit. 1 whole onion, 1 bell pepper, 2 ribs celery, 3 cloves garlic, plus any additional peppers or garnishes you want.
Dump your ground meat in the pot and chop it up with your spoon. Cook until just brown and then set aside in a large bowl or plate.
Add some oil to the pot (maybe a tablespoon???). When the oil is hot — let me say it again — WHEN THE OIL IS HOT, throw in your chopped onion, bell pepper, and celery. You should get a satisfying sizzle... the singular pleasure contained in this sound is the entire point of cooking. When you hear that sizzle, you get excited. It's on. You got this.
Cook until the veggies start looking translucent.
Toss in the garlic and add the can of tomato sauce and green chiles.
Add the ground meat back into the pot and stir.
Add: 5 tablespoons chili powder, 1/2 teaspoon cumin, 1 teaspoon oregano, 1 teaspoon salt, and 1/4 teaspoon black pepper. If you're doing a spicy variation, this is also where you add any cayenne pepper, crushed red pepper, jalepenos, hot sauce, etc, etc, etc.
This shit's starting to smell good, ain't it? Dump in the cans of chopped tomatoes, kidney beans, and red beans. Stir it up good, turn it up until it bubbles and then turn it down to a simmer. Once it's simmering nicely, you can turn it down to medium-low heat, so it's just bubbling, put a lid on it, and go do your laundry.
Stir it every so often, and in about 45 minutes, you'll have a damn good chili to eat for like a week.
