If the OP has been off grains for a while he may test negative for celiac's regardless of his true status. It does sound strange, and I'm curious as to how you know that you do better on a seafood diet. While I'm not doubting the possibility, I just want to know how its possible to come to that conclusion I love fish.
I don't know what kind of recipes you do but with salmon I adore salmon bacon - throw the fillet on a hot skillet skin-side down with your fat and seasonings of choice, cook 2-3 mins, slip the skin off and continue to fry it while cooking the fillet as you like. I learned that from MDA so that might be an old one but hey, I love it. I also like tilapia pan seared in butter, lemon juice, and garlic. Or a butter-white wine garlic and onion reduction is really easy and lends a wonderful flavor to fish. The white wine and butter combo is also great for mussels, as I recently discovered. With some caramelized red onions. Mmmm... Sorry, I'm no good for most shellfish recipes, although on thefoodee.com (great paleo recipe site) they have some awesome recipes for fish stews on there that I really want to try, some of which don't have nightshades, as I'm currently off them also. Aaaand sorry I don't have more. I like salmon with either a plain salt/pepper/garlic/onion combo, before my no-nightshades I would toss some cayenne and paprika on there if I wanted spicy, or salt and fresh dill, or a dried sweet herb mixture, like lemongrass, sweet basil, etc. My rotations are pretty basic and probably boring but... eh.
P.S. - Rasputina, I have celiac's as well and have recently decided/discovered that asparagus does horrible things to my stomach. Do you (or the OP) have this issue as well?
