Cut each brat into thirds.

Pour a bottle or can of beer into a pot large enough to fit all the brats comfortably. Fill the rest of the pot up with water so that it is about 2/3 full. Bring to a boil.

Once the liquid is boiling, put the brats into the liquid. Boil for about 15-20 minutes or until the brats are cooked thoroughly.

Cut the bell peppers and onion into large pieces.

When the brats are done cooking, drain the water from the pot. Allow the brats to cool.

Thread the brat pieces, onions and peppers on to kebab skewers. Metal skewers hold up longer and are easy to reuse. Place the kebabs on a platter. 

Pre-heat your grill on high until it is about 400-500 degrees for 5-10 minutes. Turn the heat down to medium-medium low.

Cook the beer brat kebabs until the kebabs are browned and the vegetables are tender and cooked.

Keep turning the kebabs about every 5 -10 minutes. The brats are already cooked so you are only browning them. But the onions and pepper need to be cooked. 

Remove kebabs from heat and serve.
