Prepared, snack-y, or finger foods are great - we live on things like hummus, cheese and crackers, and cut-up fruits. Think simple: sandwiches for lunch with cold cuts or tuna salad.
, try equipping with unbreakable melamine dishes & plastic cups from Target, you don't really need the high-priced stuff from West Marine till you know what your priorities are for your personal style. Buy soup bowls twice as deep as you normally would and fill them only 1/2 full so there's room for the food to slosh around if its a little rough and not end up in your lap. Ditto for cups, don't fill anything to the brim.
Leave aboard a small stash of pantry-type food that doesn't need refrigeration and is ready in a flash in case you get in late: canned soup or stew, pasta and sauce, minute rice (substitute your favorite here). And a bottle of red wine for sunset - it doesn't need refrigeration either!
