BBQ hamburgers

Something simple and interesting that I tried, hamburgers on the grill (makes about 10 small burgers).

500g ground beef, thawed
1 onion, finely sliced into cubes
3 tbsp pepper
2 tbsp corn starch
dash of herbs or spices
pinch of salt

Lettuce, cut into strips
Tomatoes, sliced
Cheese slices
Burger buns

Mix well the ground beef, onion cubes, pepper, corn starch, herbs or spices and salt. Roll the beef mixture into patty-size balls. When ready to barbeque, press the balls into hamburger patties and then grill. Depending on the heat, flip the patty after about 15 minutes. Grill the other side. Continue grilling until both sides are almost done. In the meantime, toast the buns on the grill. Place a slice of cheese on the top of the patty. When the cheese melts, remove the hamburger patty and place on the bun. Assemble the burger with lettuce and tomato slices, and serve.
