Spicy Sloppy Joes

This is one of those childhood classics that I remember as a child. They are cheap, easy and liked by kids everywhere. As an adult I prefer my Joe a little spicier, but feel free to ease up on the heat according to the tastes of your guests.

1 lb ground beef
1 small onion, minced
2 cloves garlic
1-2 Tbsp spicy mustard
1 stalk celery, sliced
1/2 green bell pepper, diced
1 Tbsp Worcestershire sauce
1-2 Tbsp brown sugar
3/4 cup ketchup (or tomato sauce)
dash of chili (adjust to your tastes)
salt and pepper to taste
1 Tbsp olive oil
sandwich buns

Heat oil in a skillet and saute onion, garlic, bell pepper and celery, seasoned with salt and pepper. Cook for 5-7 minutes, then add beef and cook until no longer pink. Drain off fat. Add ketchup, Worcestershire sauce, mustard, and sugar to beef mixture and bring to a boil. Reduce heat and simmer for 20-30 minutes, then scoop into sandwiches and serve.
