Homemade Sloppy Joes

These are probably my favorite sloppy joes in the entire world! My sister won an award for them and it's so funny because the recipe is so simple. I bet you already have all the ingredients for these in your home right now. Yum!

(Hint: I like a little smokier taste so I go a little heavy on the Worcestershire sauce)

1 lb. ground beef
1 medium chopped onion
¾ c. ketchup
T Tbsp. brown sugar
1 tsp. Worcestershire sauce
1 to 2 Tbsp. prepared mustard
2 Tbsp. butter

Brown meat and onions together. Drain fat. Combine remaining ingredients together in bowl. Add to the hamburger mixture. Simmer beef mixture. Serve on toasted hamburger buns. Serves 4 to 6.
