The only way I make up my pheasant is by grilling it. I marinade it in a mesquite marinade by McCormick for a minimum of 4 hours (the package says 15 mins, but I think it tastes better when I get it ready in the morning). No other seasoning is needed.
As for fish, again, I marinade them and put them on the grill. This marinade I make, using butter and lemon juice (put it in the microwave to melt the butter down). I put the fish fillets in a cake pan and spread the marinade over them. Sprinkle some lemon pepper on top, cover the pan with tin foil, and put on the grill. And let it cook until the juices are almost gone, then enjoy.
Hope that helps.
