This is very simple, but I like the combination:

Put a piece of trout on a large piece of parchment paper. Fold the edges to make a packet.

Bake until cooked. I baked from frozen, so it took about 20 minutes.

Meanwhile, slice an avocado. After the trout is done, put it on the plate with the avocado.

Sprinkle lemon or lime juice, soy sauce, and sriracha over the avocado and trout.
