Lemon zest & dill, with a yogurt drizzle on top after cooking

Ginger, honey, and soy sauce

Lots of chopped fresh herbs - basil, parsley, thyme, chives, oregano - with olive oil and salt

Finely chopped celery adds a nice subtle crunch. Or pickle relish.

Small adjustments that make a difference - I sauté the onions in butter first, use soft bread crumbs instead of crackers (1 slice of wheat bread per pound of salmon) and add Old Bay (about 2 teaspoons) plus some blackening seasoning for a bit of kick. No need to use salt if you use both of those. Also, lots of good pepper.

Canned salmon, green pepper, onion, cracker crumbs, egg, tsp. Dijon mustard, salt/pepper
