Recipes for so-so "fresh" tuna

Trying to think outside the box for that tuna we all see at the grocery store that's a good price but not exactly fresh? I saw 2 medium tuna steaks the other day for $8. The flesh was separating badly, looked "dry, but not yet brown. But I've been told it browns fairly quickly and that's not necessarily a sign of it being bad.

I'm talking things like smoked tuna dip for things like a tuna melt or tuna salad, etc. Recipes for cooking it through and adding ingredients to it, the opposite of a seared steak.

Any outside of the box recommendations?
