Sweet and Savory Meatballs

From: https://jamiecooksitup.net/2014/03/sweet-and-savory-bbq-meatballs/

MEATBALLS:
1 onion, finely chopped
1 1/2 sleeves saltine crackers
2 pounds ground beef (I used 9% lean)
3 eggs
salt and pepper
3 Tb honey mustard
1/2 C ketchup
1 tsp Worcestershire sauce

SAUCE: 
1/4 C ketchup
3/4 C sweet baby rays
1 C brown sugar

1. Preheat your oven to 400 degrees.
2. Chop an onion up into small pieces. Now, just a word of caution here. Chop the onions much smaller than the onions you see in this picture. Mine ended up being a bit too big and I wished I had taken the time to chop them in to fine little pieces.
3. Pour 1 and 1/2 sleeves of saltine crackers into a gallon sized Ziploc bag. Crush the crackers with a rolling-pin until they are all crumbly and wonderful.
4. Into a large mixing bowl place the cracker crumbs, 2 pounds ground beef (I use 9% lean), 3 eggs, salt and pepper, 3 Tb honey mustard, 1/2 C ketchup
and 1 tsp Worcestershire sauce. Get your hands down into the bowl and mix all of the ingredients together well.
5. Line 2 large cookie sheets with tin foil and spray it with cooking spray. Roll the meat into 2 inch balls and lay them out evenly on the trays.
6. Bake them in the oven for 20 minutes.
7. While the meatballs cook away, combine 1/4 cup ketchup, 3/4 cup Sweet Baby Rays BBQ sauce and 1 cup brown sugar.
8. When the meatballs have a nice, crispy,  dark brown exterior take them out of the oven and drizzle about 2 teaspoons of sauce over each one. Pop them back in the oven for 15 minutes to allow the sauce to heat through and get all sticky and marvelous.
