I made these for dinner last night. Always looking for ways to get more veg in the diet, but my husband wasn't thrilled about the idea of cauliflower tacos. He's a meat guy. However, he seemed to enjoy them anyway. I used 2 good sized chipotles and a tsp of adobo in the sauce and felt it still could have had more heat, but we like spicy so others may not agree. The lime really tempers the heat more than you might think. I chopped my cauliflower ahead of time to save prep time, which helped this come together easier on serving night. Next time, I'll prep the sauce ahead too. I used feta, red cabbage, thin red pepper strips, and avocado slices as my garnish. Delish!
