Pork tenderloin is a crowd pleaser—tender, lean, and easy to cook. This one gets even better with a rich, silky pan sauce made with butter, lemon juice, and a pinch of crushed red pepper. The best part? It’s a one-pan meal (which means easier prep and less clean-up). Cook the pork and shallots, sauté the chard stems and leaves, and make the sauce all in the same pan, which will ensure the flavor of the dish builds with every component. We love this healthy meal as-is, but you could always serve the pork and chard over brown rice to add a whole grain.
