Preheat oven to 375°F. You will need an 8x8-inch oven-safe casserole dish.

In a medium skillet, on medium-high heat, add the olive oil and ground beef. Cook the meat for 5 minutes, or until browned and cooked through. Transfer the cooked ground beef to a paper towel-lined plate and drain any excess fat from the skillet. Make sure to leave 1 tablespoon of fat in the pan to saute the vegetables in.

Add the chopped onions and red bell pepper to the same skillet that you cooked the ground beef in after the excess fat has been drained off. Saute for 5 minutes or until the vegetables are tender.

To the vegetables, add the packet of sloppy Joe seasoning, beef broth, ketchup, tomato puree, tomato paste, Worcestershire sauce, salt, and black pepper. Stir to combine. Add the cooked ground beef back to the skillet and simmer the mixture on medium heat for 5 minutes. Turn off the heat to the skillet.

Stir in 1 cup of the shredded Colby jack cheese. Transfer the sloppy Joe dip mixture to the 8x8 casserole dish. Top the mixture with the remaining 1 cup shredded Colby jack cheese.

Bake for 20 minutes or until the cheese is melted and the dip is bubbly and hot.
