Fish amandine sounds great! i'll try it out!Since it's nothing specific I'll give two very different general suggestions
I'm just a part time prep cook, these are just two I enjoy the most
First off your classic fish amandine, fish and almonds and great beans. Blanch the green beans and quickly pan sear the fish, and then bring some butter to a boil till it turns brown and nutty. Cook the fish and green beans with almonds in the brown butter till they're done. Add a bit of parsley and lemon
You can also make fish en papillote. Get some onions, garlic, lemon zest, chillies, and a bit of coriander, and add them to fish in individual parchment pockets and bake them at 450F
These are just general directions, I'm not good with giving specific recipes, hope it helps though.
