We are having a BBQ of about 16 or so people for 4th of July. We don't eat meat, so we usually do a portobello burger or fish kebabs as a main course when we BBQ (along with plenty of veggies and side salads). I'd love to do some kind of fish but we're trying to avoid spending a ton of money. Any suggestions for recipes that stretch the use of the fish so that I don't have to buy the equivalent of 1/2 pound per person? I initially thought of salmon burgers, but most of the recipes I've used in the past still have a high fish: other ingredient ratio. Thanks in advance!
