Make the Crispy Breaded Cauliflower (about 40 minutes total; use the remaining time to complete the steps below.)
If using purchased refried beans, taste and if needed, mix with 1/2 teaspoon cumin and/or a pinch or two kosher salt. (Or, you can make our Supremely Simple Refried Black Beans but for this recipe we preferred using storebought so we could focus on the cauliflower!)
Thinly slice the cabbage, enough for 2 cups. Mix it with 2 tablespoons lime juice and a pinch or two of salt. Allow it to stand at room temperature until serving.
Warm the tortillas, or char them by placing them on grates above an open gas flame on medium heat for a few seconds per side, flipping with tongs, until they are slightly blackened and warm.
Chop the cilantro for a garnish
To serve, place refried beans in a tortilla, top with cabbage, breaded cauliflower, sauce, and cilantro. Serve with lime wedges to spritz prior to serving. (If you have leftover cauliflower, you can reheat them in a 350F oven for 10 minutes, flipping once.)
