One cannot stress enough the importance of water, especially in the Florida summer heat. Bring lots of it in big jugs and bring smaller reusable bottles for portability and sharing.
While camping, a vegetarian diet is easier to maintain because not as many items need refrigeration, causing you less worry about the freshness of your food and less weight to carry.
Pastas, rice and breads/crackers are filling and easy. (My personal favorite is to bring bagels for breakfast.) You can spice them up by adding veggies or making a classic peanut butter and jelly sandwich.
Bring some snacks, such as cereals or granola bars, along with fruits for a quick bite in between meals.
Don't forget dessert! S'mores are a traditonal camping favorite.

Coleman makes a variety of two-burner propane camping stoves.
