Warmth your largest ovenproof skillet or sauté pan over medium-high warmth. As soon as sizzling, add oil, and as soon as the oil is sizzling, add the onion, garlic, jalapeño, and bell pepper and cook dinner till the the elements start to melt, 4 to five minutes. Add the cumin, first 2 teaspoons chili powder, and tomato paste, and cook dinner for 1 minute. Add diced tomatoes and let simmer for 1 minute, then add the beans and simmer for two to three minutes. Style the combination and add salt; I discover I would like between 2 to three teaspoons of kosher salt (Diamond model) to get the extent proper however alter it to your style. Add final 1 teaspoon chili powder if wanted to your desired warmth degree. Add the corn and spinach and stir till the spinach has wilted and every thing is heat. Style for seasoning once more and alter as wanted. Squeeze juice of half a lime over.

In the meantime, warmth your oven’s broiler, and if it doesn’t have a broiler, warmth it as sizzling because it goes.

In case your skillet isn’t ovenproof, pour combination right into a baking dish. Combine jack and cotija cheeses and sprinkle combination over the beans. [The smaller amount of jack cheese covers the pan less thickly than shown here, and allows more sauce to bubble through. The larger amount is never unwelcome.] Switch to broiler and cook dinner till cheese is melted and browned on high. Eat immediately with tortilla chips, sizzling sauce of your selection, and should you’re me, a squeeze of juice from the second half of the lime.

Do forward: Whereas the entire dish reheats nicely in a 350°F oven, should you’re planning to eat it later, I’d wait to place the cheese on till proper earlier than you serve it as a result of cheese is at its most stretchy/gooey the primary time it melts.
