i'm assuming you mean savory.. i have a TON of sweet recipes.
i like to add them toasted and ground to chili with a touch of dark cocoa powder.
breading for fish - toasted cumin seeds, coriander, salt, pepper, toasted pumpkin seeds, toasted hazelnuts, smoked paprika - ground to breading consistency
roasted - with butter, a little honey, brown sugar, rosemary, paprika, salt, pepper, and sometimes a bit of orange zest
"pesto" - toasted hazelnuts, olive oil, cocoa powder, heavy cream, marsala, salt, pepper, parmesan, (optional) pepper flakes, and a dash of nutmeg
i'm not a big nut fan, but i like using hazelnuts...
