Preheat the oven to 400 degrees.
To make the meatballs place the egg in a large bowl and beat. Add in the ground beef, breadcrumbs, garlic cloves, salt, pepper, and Worcestershire sauce. Mix until just combined.
Line a baking sheet that has sides with foil.
Form the beef mixture into 1-1 1/2 inch meatballs and place on the baking sheet.
Bake for 20 minutes, turning one time, until they have browned and are cooked through.
Meanwhile, combine the soy sauce, Thai sweet chile sauce, rice vinegar, honey, water, and cornstarch in a bowl. Mix well.
Pour the sauce into a medium sized skillet and heat over medium heat.
Add the meatballs to the skillet and toss to coat.
Serve warm.
