Step 1

Preheat the oven to 350°F (177°C).

Step 2

Heat the oil in a 10-inch skillet over medium heat. Add the ground Italian sausage and break it apart with a spatula. Cook, stirring occasionally until the sausage has browned and has cooked through, about 5 minutes.

Step 3

Add chopped onions, chopped green bell peppers, and minced garlic to the pan and cook for 2 minutes, stirring frequently until the onions have softened. Using a slotted spoon, scoop the sausage and vegetables onto a paper towel-lined plate to drain off the grease.

Step 4

Coat the bottom of a 10-ounce ramekin with 1 tablespoon of marinara sauce.

Step 5

Line the bottom of the dish with the pepperoni slices.

Step 6

Add the sautéed sausage and vegetables to the dish, smoothing it out into an even layer.

Step 7

Spoon the remaining marinara sauce on top of the sausage layer.

Step 8

Top with shredded mozzarella cheese and place the ramekin on a rimmed baking sheet to catch any possible spills. Bake for 10 minutes.

Step 9

Remove the pizza bowl from the oven and let it rest for 5 minutes before enjoying it.
