Cook bacon over medium heat in large oven-safe skillet until desired level of crispiness. If you don’t have an oven-safe pan, you can transfer to a baking dish before putting in the oven. Take bacon out with slotted spoon and set aside on paper towel lined plate.
Add onion, bell peppers, and corn to skillet and cook until onions are translucent. Stir in chili powder, cumin, coriander, dried oregano, salt, sugar, pepper and garlic. Cook for about 5 minutes.
Add lentils, crushed and diced tomatoes, macaroni, and water. Bring to a boil. Then reduce heat to medium low. Cover and cook for 20-25 minutes until macaroni is cooked all the way through, stirring occasionally.
Stir in the bacon pieces. Top with cheese. Bake for about 5 minutes until cheese is melted. Broil for a few minutes to get the top extra bubbly, if desired.
