Step 1

Preheat oven to 400 degrees F.

Step 2

Heat the olive oil in a large skillet over medium heat. Cook the onion, bell pepper, and jalapeno until they begin to soften, about 4 to 5 minutes.

Step 3

Turn up the heat to medium-high and add the ground beef to the pan. Cook the meat while breaking it up with a spatula until brown all the way through.

Step 4

Add the tomatoes, black beans, frozen corn kernels, and spices. Cook for another 2 to 3 minutes while stirring occasionally to thoroughly combine the mixture.

Step 5

Pour the beef mixture into a rectangular baking dish, top with cheese and then frozen sweet potatoes. Bake for 30 to 35 minutes or until the sweet potatoes are heated all the way through.

Step 6

Serve topped with sour cream if desired.
