I know this is a backpacking light forum and what I am about to say borders on heresy. For relatively short trips (one or two nights out on the trail) you can carry just about anything, especially for your evening meal. The ingredients for a lot of fine light weight meals can be obtained at any supermarket. There are some dandy recipes right here on this forum.

Just a word about island parks like Isle Royale. The trip over the water really cuts down on visitation; Isle Royale is frequently the least visited of the National Parks; Channel Islands National Park, where I worked for several years, is often third from the bottom. Unlike the drive by parks, some planning is required. You do avoid the teeming hordes however. And, for that matter, the trip across the water can be a significant highlight of the trip.
