Preheat your oven according to the instructions in the Texas toast package. Place the Texas toast slices on a baking sheet lined with aluminum foil or parchment paper. Toast them in the oven according to the package instructions and then remove and set aside.
In a large skillet, brown the ground beef until it's no longer pink. Add in diced onions and diced green bell peppers to the skillet. Sauté them until tender.
Return the cheesy Texas toast back into the until the cheese is melted and slightly bubbly. Serve your Texas Toast Sloppy Joes immediately while warm, and enjoy!
