I am not a fan of fish fingers TBH. My boys have had them once at a friend's place and that's it. My main concerns are the salt and preservatives, and also the fish used in them is usually the species that are connected with high mercury levels or other contanimation. You can get some brands which aren't, but they are harder to find.

I try to ensure the boys have fish at least once a fortnight. The main ways we have it are salmon patties or grilled fish. Grilled fish is really easy to do, and DH loves to do it on the BBQ as well which I love. For a special treat they also get fish and chips occassionally although until recently I would order them grilled fish, or pull the crumbs off before giving it to them. Other things you can do are tuna mornay, or baked fish (there are some really yummy recipes for cooking fish in the oven if you google it). GL, fish is scary to cook at first, but once you've done it once or twice, you'll see how easy it actually is!
