Blend the green base. In a blender, combine cilantro, spinach, jalapeño, lime juice, garlic, olive oil, salt, and 1/2 cup of the broth.
Blend until smooth and vibrant.
Cook the rice. Rinse rice until water runs clear. In a saucepan, combine the remaining broth with the green blend. Bring to a simmer, stir in the rice, cover, and cook over low heat until tender (about 15 minutes for white rice; 35–40 for brown).
Let steam off heat for 10 minutes, then fluff.
Sauté the aromatics. In a skillet over medium heat, warm olive oil. Add red onion and cook until soft, 3–4 minutes. Stir in garlic, cumin, and smoked paprika for 30 seconds.
Simmer the beans. Add black beans and broth to the skillet.
Simmer 5–7 minutes until saucy. Season with salt and pepper.
Mix the mango topping. In a bowl, combine mango, bell pepper, red onion, cilantro, lime juice, and a pinch of salt. Toss gently.
Whisk the crema. For tahini: whisk tahini, lime juice, and water until pourable; season with salt.
For avocado: mash or blend avocado with lime juice and a splash of water; season.
Assemble the bowls. Add a bed of green rice. Top with black beans, mango salsa, and any extras like corn or pepitas. Drizzle generously with crema.
Finish and serve. Add a squeeze of lime and a sprinkle of cilantro.
Taste and adjust salt or heat if needed.
