Ingredients

• 1 lb ground beef
• 1 medium, finely chopped yellow onion
• 1 small, finely chopped green bell pepper
• 2, minced garlic cloves
• 3/4 cup ketchup
• 2 tbsp tomato paste
• 1 tbsp Worcestershire sauce
• 1 tbsp brown sugar
• 1 tsp yellow mustard
• 1/2 tsp salt
• 1/4 tsp black pepper
• 1 tbsp olive oil
• 4 soft hamburger buns
• 2 tbsp, melted butter

Instructions

1. Step 1: Heat 1 tbsp olive oil in a large skillet over medium heat. Add 1 medium finely chopped yellow onion and 1 small finely chopped green bell pepper; sauté for 5 minutes until softened and fragrant.
2. Step 2: Add 1 lb ground beef to the skillet, breaking it up with a wooden spoon. Cook for 6-8 minutes until browned and no pink remains, stirring occasionally.
3. Step 3: Stir in 2 minced garlic cloves and cook for 1 minute until fragrant. Then add 3/4 cup ketchup, 2 tbsp tomato paste, 1 tbsp Worcestershire sauce, 1 tbsp brown sugar, 1 tsp yellow mustard, 1/2 tsp salt, and 1/4 tsp black pepper. Mix well and simmer on low heat for 10 minutes, stirring occasionally until the sauce thickens and coats the beef.
4. Step 4: Meanwhile, preheat the oven to 350°F. Lightly brush 4 soft hamburger buns with 2 tbsp melted butter and place them on a baking sheet. Warm in the oven for 5 minutes until slightly toasted.
5. Step 5: Spoon the sloppy joe mixture generously onto the warmed buns and serve immediately for a kid-friendly, hands-on meal.
