Tip - Best Inexpensive Fish or Seafood for Grilling? — Good Questions

Q: I am hosting a BBQ for around 10 to 15 close friends. My boyfriend and I are pescatarian, and while I am open to inviting the carnivores in attendance to bring their own hot dogs or other meat, I want to make one "main" that everyone can eat, too. So I am looking for a fairly inexpensive fish (since I need to buy a lot of it) that will be good prepared in a simple way on the grill. Any thoughts and/or recipes? Sent by Arielle
