Place the butter in a large nonstick skillet set over medium heat. Once the butter melts, add the berbere and cook, stirring, until the spices sizzle and smell fragrant, about 30 seconds. Add the kicha pieces and sprinkle with the salt. Cook, stirring, until all the pieces of kicha are coated with the spiced butter and warmed through, about 3 minutes. Transfer the mixture to a serving platter or individual bowls, top with the yogurt, and serve immediately.
