We had a kitchen so we ended up doing Costco, and getting some food from safeway. We also went to the fish market that was near us in Napili, and got some fresh fish. Those ended up being the best meals. When we were in Lahaina for surfing lessons, we stopped at cheeseburger in paradise. Decent burgers, great atmosphere.
