Same here. I'll add a lot of seasoning but not usually marinade unless it's ceviche. However, I used a store-bought one the other day on chicken thighs, but it was recommended for fish and I think it would be good on a neutral fish. It was lime, cilantro, jalapeno, and chipotle. I'm sure there was salt and other stuff in there. It would be a different take on cblaisd's idea with the citrus and cilantro plus a little spice. I would think honey might char a bit on the grill but not sure.
