The place I work at (small boutique hotel and dining room), we offer a picnic lunch for guests to take with them as they explore the area. We offer them year round, but being in New England we really only sell them frequently in Summer and Fall foliage. I'm looking for a few ideas to spruce up our offering a bit. We do the normal ham/roast beef/turkey (all made and sliced in house) and a nice oil packed tuna salad. We keep the tuna in cans in the pantry and the sliced deli meats frozen in portions. I know not ideal, but we don't go through them fast enough not to freeze. We'll do a veggie sandwich upon request. In previous years we've done variations of chicken salad (Thai peanut, curry/apple, etc) but I want to get away from chicken salad since ordering is somewhat unpredictable and keeping prepared chicken salad around all the time doesn't seem economical. We frequently don't get the picnic orders until later in the evening, so it becomes arduous to pull a frozen chicken breast, thaw it, cook it, and make the salad all potentially after service or just at the end. In any event, looking for ideas for sandwiches that maybe aren't super common or ubiquitous, but also maybe where the ingredients keep or store well for long periods. I had a couple of quick thoughts pimiento cheese sandwich mozzarella with tomato and pesto (maybe tomato jam in months where tomatoes aren't in season) Any other ideas? No chicken salads please. Creative tuna salad ideas?
