Preheat oven to 425º F.
Start the rice: Make the rice as per package directions. Make it in the Instant Pot for fuss free rice.
Finish the rice: To finish the rice, fluff with a fork then stir in the chopped cilantro, lime juice, and salt.
Roast the sweet potatoes: Toss the sweet potato cubes with the olive oil, spices and lime juice. Arrange in a single layer on a baking sheet and roast until crispy on the outside (~20-25-minutes), tossing halfway through to prevent burning.
Roast the peppers & onions: Slice the peppers into strips and slice the onions. Toss with olive oil, salt, and oregano. Arrange in a single layer on a baking sheet. Roast until tender crisp and slightly caramelized on edges stirring one or two times (~15-20 minutes).
Sauces & salsas: Make the Tex-Mex cashew cream, prepare avocado and tomatoes or my quick pico. Season the black beans: Drain and rinse the black beans. Toss with a handful of chopped cilantro, a sprinkle or two of salt, and a squeeze of lime.
Time to dig in!: Build your bowl with rice, sweet potatoes, black beans, avocado, tomatoes, peppers & onions, shredded romaine, and extra toppings of your choice. Top the bowl with chopped cilantro, a squeeze of lime, and a generous drizzle of spicy cashew sauce.
