A simmered blend of black beans, rice, sweet peppers and poblanos that's a one-pan taco party main attraction.
Set your oven to 400° and let it come up to temperature. Meanwhile, put a large (10-12 inch), high-sided skillet over medium heat and add the 2 tablespoons olive oil to the pan. (This is also a good time to rinse and soak your rice if you have not done so already. See TIP A.)
Add the finely diced onion, sweet peppers, poblano peppers, jalapeño (if using), and garlic to the pan. If desired, you can reserve a small handful of mini sweet pepper rings to top the skillet later (as shown in image). Stir to coat the ingredients in the oil and let sizzle and cook 3-5 minutes. Meanwhile, add 1.5 teaspoons kosher salt (reserve remaining salt) and all of the seasonings (chili powder through black pepper) to the pan. Stir again.
Next add the rinsed and soaked rice to the pan. Let the rice toast briefly against the bottom of the skillet (about 1-2 minutes). Then add the water and lime juice. Stir again.
Lastly, add the rinsed and drained black beans and remaining 1 teaspoon kosher salt to the pan. Stir to evenly distribute all of the ingredients and then smooth the top of the mixture so that it is relatively flat. Cover the pan with a tight-fitting lid or piece of aluminum foil. Reduce heat to low and let simmer for 20 minutes.
After 20 minutes, remove the cover and sprinkle any reserved sweet pepper rings and 1/2 - 3/4 cup cheddar cheese over top. Transfer the skillet to the top rack of a preheated 400° oven for 10 minutes or until the cheese has melted and turned slightly golden.
When done, top the warm skillet with chopped fresh tomatoes and cilantro leaves (if desired). Serve with warm corn or flour tortillas, tortilla chips, and a few of your favorite taco toppings. Enjoy!
TIP A: For this recipe, it's important to use white basmati rice so that the cook time matches the rest of the dish (brown rice tends to take a much longer time to cook). Before adding the rice to the skillet, be sure to thoroughly rinse it—at least 30-60 seconds under cold, running water. Then give it a headstart by letting it soak in room temperature water for 15-20 minutes. Thoroughly drain the rice before adding it to the skillet.
TIP B: Warm—even slightly charred tortillas—make all the difference for any tacos. The easiest method is to wrap the tortillas in foil and put them in a low-heat oven (about 250°) for 10-15 minutes. If you wish to give them a bit of char, then you can put them individually over your stove's gas burner (set to low) for 30-60 seconds per side. Once charred, wrap the tortillas in foil and set them in a low-heat oven until ready to serve.
