Ingredients

• 1 pound ground beef
• 1 egg
• 1 cup instant oatmeal
• 1/2 cup ketchup
• 2 tablespoons prepared mustard
• 1 teaspoon salt
• 1 teaspoon ground black pepper
• 6 hot dog buns
• 6 slices American cheese

Instructions

1. Preheat oven to 350 degrees F (175 degrees C).
2. Mix ground beef and egg together in a large bowl; add oatmeal, ketchup, mustard, salt, and pepper. Mix well.
3. Arrange hot dog buns on a baking sheet. Spoon ground beef mixture into each bun.
4. Bake in the preheated oven for 10 minutes. Add an American cheese slice to each 'boat burger'; continue baking until ground beef is fully cooked and buns are crispy, 10 to 12 more minutes. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).
