Heat oil in a large skillet over medium-high heat. Add the diced onion and cook for 3–5 minutes, until soft. Stir in garlic and cook for 20–30 seconds.
Push onions to the sides of the skillet. Add ground meat to the center. Let sear then break it up with a wooden spoon and cook for 5–8 minutes until no longer pink, but not all the way cooked through. Drain excess liquid if needed.
Stir in taco seasoning. Cook until the meat is fully browned. Add the undrained fire-roasted tomatoes and scrape the bottom of the pan. Simmer for 2–3 minutes until most of the liquid is absorbed.
Add frozen corn, black beans, and drained green chiles. Stir to warm through.
Reduce heat to low. Add the shredded cheese a handful at a time, stirring between each addition until melted and fully incorporated.
Remove from heat. Sprinkle with green onions and cilantro if using. Taste and adjust seasonings. Serve immediately with chips or your favorite toppings (see note 3).
