I cut beef (in this case) in cubes and marinated it in zesty Italian dressing overnight (shown in zip-loc bag) and then cut peppers, onion and pineapple into chunks.
All put together ready for the grill. Beef, peppers (3 different colors) pineapple, onion and tomatoes.
On the grill, I cook over coals and turn till they look done, usually about 20 minutes with a low heat.
With beef the only meat they can be a tad rare with no problem, not so with chicken or pork.
Ready to eat left, with corn on the cob and fresh french bread. As you can see I really like to rough it.
