Cauliflower steaks are potentially one of the greatest vegetarian dinners of all time. Theyre hearty, fork-and-knife numbers that even any meat-obsessed person can get behind. The sauce is a spanish-inspired romesco sauce, made with almonds, roasted red peppers, and sherry vinegar. Here, almond butter is not only a shortcut to flavor but it also makes for a smoother sauce. And the arugula-radish salad is the peppery sidekick that brings it all together. Pro tip: save the cauliflower trimmings to make cauliflower rice. Pulse them in the food processor or use a box grater to turn them into small pieces.
