Heat your instant pot over SAUTE. Add the avocado oil, and saute all the vegetables with the salt + pepper for 7-10 minutes until soft, stirring occasionally.
2 tablespoons avocado oil, 1 yellow onion, 1 zucchini, 1 yellow squash, 1 red bell pepper, 4 ribs of celery, 2 cloves of garlic, 2 teaspoons kosher salt, 2 teaspoons black pepper
Add the ground beef and break it up with a wooden spoon. Cook for 5 minutes, stirring occasionally.
2 pounds ground beef
Add in the canned tomatoes, tomato sauce, spices + chicken stock. Stir to combine.
2 14.5-ounce cans diced fire roasted tomatoes, 1 15-ounce can tomato sauce, 2 4-ounce can diced green chiles, 3 tablespoons chili powder, 1 tablespoon cumin, 1 tablespoon oregano, 1 tablespoon smoked paprika, 1 cup chicken stock
Close with the lid of your instant pot, and make sure the vent is at SEALING. Hit CANCEL, then cook on HIGH PRESSURE for 15 minutes. Will take about 10-15 minutes to reach pressure, then it will start counting down from 15. After the 15 minutes is up, do a QUICK RELEASE, where you move the valve to VENTING to release all the steam. Once all the steam is gone and the float valve has dropped, you can safely open the instant pot.
Serve warm topped with your favorite toppings: sliced avocado, jalapeños, cilantro, etc.
Will keep in an airtight container refrigerated for 5 days, or frozen for 6 months.
