We should be able to grow some typical staple crops like:
Corn
Tomatoes
Strawberries
Potatoes
Corn could be ground up into a flour product, and used in "corn and mussels" which is something in my region we have EVERY thanksgiving, and is the bomb.
Plus if those infernal mussels are still in game, we NEED something to do with all the million bazillion mussels people grind up pearl hunting, but they suck as a stand alone food. We need a product we can get higher quality, to bring up the quality of the mussels in what ever food they go into. There really aren't any or many recipes for mussels.
Tomatoes could be used to invent sandwich recipes. Who really hasn't thought about Bear Burgers and the like? Bear-Lettus-Tomato anyone? xD
Strawberries could be used with some of the other berry fruits in like a fruit salad, fruit parfait, or the like.
Potatoes are just really common through-out the entire world and could be a good addition, especially if it were a con mixer food. Baked Cheesy potatoes anyone?
