Last night's dinner was very simple -- grilled trout, fresh bread, and leftover spaghetti squash. [Every few weeks we buy a relatively large spaghetti squash, and eat it every other meal for ~3 meals. It's a time saver, and we like it.]
One of our favorite recipes for trout or salmon is really tough to make -- it takes 2 ingredients -- fish & pesto. This can be baked or grilled, although we prefer grilled.
Preheat the grill (ours is gas), turn all burners to low, put the fish-on-foil on the grill and leave (covered) it for 20 minutes. If a piece of salmon is thicker, increase time to 25 minutes.
If doing this in the oven, bake at 350 F for the same times.
The pesto releases a fair amount of oil, so turn the edges of the foil up, so the oil doesn't drop and burn the fish.
The skin burns to the foil, and I use a large grill spatula to carefully separate the meat from the skin. After the grill cools, the oil appears to be absorbed into the skin. Cleanup is easy.
If baking in the oven, line the pan with foil, else you'll be scraping that pan for a while.
A bit of pesto on the bread went well.
