ingredients

• 1/2 Tablespoon olive oil 
• 1 cup chopped yellow onion (about 1 small) 
• 1 cup chopped sweet bell pepper (about 1) 
• 1 lb. ground beef 
• 1 1/2 teaspoons taco seasoning (storebought or homemade) 
• Salt and pepper, to taste 
• 6 large flour tortillas 
• 3 cups shredded Mexican blend cheese 
• 2 tablespoons butter

cooking

1. Preheat the oven to 200 degrees. 
2. Heat the olive oil in a large skillet. Add the onions and peppers and saute until starting to soften, about 4-5 minutes. Add the ground beef and cook until browned. Drain any excess oil off the pan. 
3. Transfer the beef to a plate or bowl, and wipe out the skillet. Line up your tortillas on a large work surface, or, if you're short on space, just do them one at a time. Spread about 1/2 cup of cheese on each tortilla, covering the entire surface. Divide the ground beef evenly between the tortillas, spreading it on one half of each tortilla. 
4. Melt a pat of butter in the skillet and place the tortilla face up in the center. Cook on medium heat until well browned, then use a spatula to fold the cheese-only side over the beef side. Press down slightly to get the cheeses to melt together. Remove from the skillet and place on a wire rack in a 200 degree oven to keep warm. Repeat with remaining quesadillas.
