Ndiwo Za Mpiru Wotendera (Mustard Greens with Peanut Sauce)
2 bunches fresh mustard greens
½ teaspoon salt, divided
3 green onions, sliced thinly
½ pound cherry tomatoes, halved and seeded
½ cup peanut butter
¼ cup water
⅛ teaspoon cayenne pepper
1. Wash greens carefully and trim off any tough stems. Hold 3 to 4 leaves together and tear into small, even pieces.
2. Bring a small amount of water to a boil. Add ¼ teaspoon salt and greens. Cook until greens are tender, about 3 minutes.
3. Drain greens and press out excess liquid. Put back into the pan with the green onions and tomatoes. Cook until slightly limp, about 2 minutes.
4. Combine the peanut butter, water, ¼ teaspoon salt and cayenne to a paste. Add to the greens and cook, stirring constantly, until thickened, about 5 minutes. Add a few more tablespoons water if necessary. Serve with rice.
