Step 1

Preheat oven to 400 degrees F.

Step 2

In a cast iron skillet (or other oven-proof large skillet) heat the olive oil over medium heat. Cook the onions while stirring until they begin to soften, 2 to 3 minutes.

Step 3

Add the ground beef to the pan and cook while breaking it up with a spatula until almost brown all the way through, 4 to 5 minutes. Add the bell and hot peppers and cook until soft, another 2 to 3 minutes.

Step 4

Sprinkle the seasonings onto the beef mixture and stir until well combined. Add the diced tomatoes and corn kernels and bring to a light boil then turn off the heat.

Step 5

Meanwhile, in a small pot combine the milk, cornmeal, butter, and salt. Bring to a light boil while whisking constantly. As soon as the mixture begins to thicken, only takes a minute or two, scrape out of the pot and spread on top of the meat mixture into one even layer.

Step 6

Top with shredded cheese and bake until golden brown, about 20 minutes. If preparing in advance may take longer to bake if putting it in the oven cold.

Step 7

Garnish with sour cream, avocado and/or cilantro (if desired) and serve.
