On our last trip, I cooked up some pretty tasty skewers that were all prepped at home. Even my picky eating kids loved them. While I am all for making homemade marinades, I found that Walmart carries a great liquid Caribbean Jerk marinade. Soaked a few steaks (usually I prefer ribeyes, but sirloin works great and is cheaper) and some de-boned chicken thighs overnight in the marinade. Cut them up into small cubes along with some link smoked sausage. Cut up green and red pepper, zucchini, and onions for the skewers. Rubbed the veggies with olive oil, then ground salt and pepper on them. Put 'em all together, placed them in the fridge, and was ready to go on our trip.
After setting up our site Friday afternoon, it was a simple meal to throw on our portable gas grill. Paired it up with some corn on the cob and rolls, and we were good to go.
