Easy, everyone loves kabobs. And I love these because they're simple and quick, and everything in them is natural.
1 lb beef (sirloin, stew meat, whatever you've got handy), cut into equal sized cubes
Juice and zest of 2 limes
Veggies of your choice (I use bell peppers, red onion, and mushrooms), cut into equal sized pieces
Salt and pepper
If you're using wooden skewers, make sure you soak them in water before you use them, otherwise they might catch on fire on the grill.
In a large bowl combine the meat, veggies, lime zest and juice, and salt and pepper. Cover and place in the refridgerator for at least an hour.
Heat your grill to medium heat while you arrange your kabobs. Put the meat and veggies on the skewer; I like to alternate between meat and veggie, meat and veggie. You might like more meat, less veggie, or more veggie, less meat. It's up to you. I use one of those mesh grilling pans, so I assemble the kabobs in the kitchen on the grilling pan, and then take the whole thing to the grill for cooking.
