[food/drink] Steelhead trout with tomato relish and shallots

I usually write about things I understand or think I have some insight into. However, I've been learning to cook, so for a while I will also be posting about things I barely comprehend. Please be gentle.

1 pound steelhead trout fillets
1 medium shallot
15 grape tomatoes
olive oil
balsamic vinegar
salt
pepper
dill
