If using forbidden rice, combine in a saucepan with 2 cups water. Bring to a rapid simmer, then lower the heat, cover, and simmer gently until the water is absorbed, about 30 minutes. If you’d like a more tender grain, add ½ cup additional water and cook until absorbed. If using wild rice, combine with 3 cups water and cook as directed above.
Just before the rice is done, heat half of the oil in a large skillet. Add the garlic and sauté over low heat until golden. Add the scallions and corn kernels and sauté just until warmed through.
Transfer the cooked rice to the skillet. Turn the heat up to medium high, then add the lime juice, cilantro, cumin, oregano, thyme cranberries, and remaining oil. Stir together gently, then season to taste with salt and pepper.
To serve, transfer to an attractive serving platter and sprinkle the pumpkin seeds over the top.
