Low Sodium, but High Calorie Foods?

Options
Need ideas for high calorie and low sodium foods. I am on a low sodium diet, which is going great, however, I am not getting enough calories daily though I eat three meals and a snack each day. I don't necessarily feel hungry each day, but some days, even with eating, I'm starving come bed time.

Does anyone have an idea of a high calorie food with low sodium? Recipes welcome.

Thank you.
