I'm recently in love with my harissa and berbere pepper blends, would like to use them on a marinade for seitan, tofu or tempeh and make sandwiches or tacos. I'd like to do the tacos, really, but what other "toppings" would combine well? Definitely will use caramelized onions, but for a salsa? Are tomatoes in or out? Cilantro? And then...what beer for the other hand?
