In the final weeks before we moved from the log house to our city space, we dipped into the pantry almost every night to use up ingredients before the move. Some of our from-the-pantry creations were winners, others not so much. This red beans and rice variation, one of the keepers, came together quickly after I soaked dry beans overnight and then cooked them in the pressure cooker (I'd already run out of canned beans, which would be a fine substitute). Typically, the rice would be prepared separately, but I cooked it right in with the beans. If you omit the shrimp and use water instead of chicken stock, you'll have a hearty vegetarian main dish. Try to use homemade stock if you are gluten-free, but again, you can swap in store-bought low-sodium chicken stock. Don't wait until next year's Mardi Gras to enjoy this New Orleans-style recipe; make dinner a celebration, at any time of year.
