Having a boat is great, especially during summer, and especially if that boat is big enough to grill on. However, the entire point about being on a boat is to relax, and for most people that means that they just want to cook and not worry about any preparation. With that in mind there are a number of great foods that can be prepped ahead of time on your pontoon boat grill and be ready for when you are on the boat. Keep in mind that you will need some good sides as well to round things out, and a slaw can work wonders.
The best place to start is with the vegetables. A shish-kabob is only as good as its parts, and that means the vegetables as well as the meat; make sure that you have some good-sized chunks of fruits and vegetables and you should be good to go. Keep in mind that pineapple, oranges, and apples work well, especially when grilled, and you will want onions, bell peppers, chili peppers, tomatoes, and potatoes as well. Not only do these work well on a skewer, but they can be cooked on their own as well. Keep in mind that some vegetables, such as taro root, require cooking or you will have sick people or worse, but do not be afraid to try whatever strikes your fancy.
Corn is sort of a weird one here. Although most people will just eat the ears plain, you can also take advantage of foil: You can cover the ear in a light cheese, such as grated parmesan, and seasoning, and then grill them in the foil. This makes for a great side dish by itself. You can prepare potatoes like this as well, possibly even slicing them in half, throwing butter or grated cheese in the center, and then using the foil to put the halves back together.
Steak is always a favorite, and it can only help to marinate the meat before cooking it. A good marinate takes at least a day to soak into the meat. Make sure that the meat has been properly trimmed so that it not only cooks well but that the marinate will properly soak into it. You should debate leaving it on the bone as it makes for a more appealing entrée, even though you will need to cook it longer. If you are going to add it to the kabobs, make sure that you have good-sized chunks available.
Burgers should be in patty form before you even leave the house. Parchment paper and plastic wrap are your friends; you can use the paper to set up layers and then wrap it up in the plastic. Make sure that patties are to your taste before packaging and you should do fine. This applies no matter what kind of patties you actually use; hamburger, sausage, garden, or even eggplant patties should all be ready to go before they leave the house, and using this system allows you to even bread them ahead of time.
If you are using any shellfish make sure that it has been properly prepared. This means that the tails may need to be taken off, but it should be deveined at least. Not only do they work well with steak, but they also add a lot to kabobs. These tips should help you to really enjoy your grilling time on your boat!
