Sure. You can "oven can" any food that can be safely kept at room temperature without processing. Hence, nuts, various dehydrated fruits or veggies, pasta or grains can be oven canned.
I canned a dozen half gallon jars of oyster crackers last fall, and they are just like fresh when we open one. "Oven canning" is essentially the same as vacuum sealing.
