Bring chicken broth to a boil in a small- to medium-size pot, and then stir in the turmeric and brown rice. Bring back to a boil, stir the rice, and then lower the heat and cook for 35 to 40 minutes or until the rice is tender and the liquid has been absorbed. Remove the pot from the heat and let rest, covered, for 5 minutes.
While the rice is cooking, chop the veggies and then heat the olive oil in a large skillet (I use a 12-inch cast iron pan) over medium-high heat. Add the onion, and sauté until softened and beginning to brown, about 5 minutes. Stir in the bell peppers, jalapeño, cumin, and salt. Cook for 3 to 4 more minutes or until the peppers are crisp-tender.
Remove the pan from the heat and stir in the drained beans and the cooked rice. Stir in the cilantro and sprinkle with the cheese. For an optional garnish, sprinkle with additional cilantro. If desired, offer chopped avocado, salsa, and/or lime wedges to squeeze over the rice.
