Break down your cauliflower into bite-sized florets (see photos for reference).
Toss cauliflower with the oil and spices until evenly coated.
On a baking sheet lined with parchment paper, bake cauliflower in the oven for 25-30 minutes, stirring halfway.
Lime Rice
Add your US Grown long-grain brown rice to a pot with water. (Use as much water as the package directs - different varieties will call for different amounts).
Cook brown rice until all water is absorbed, and rice is al dente.
When rice is done cooking, add in the lime juice, lime zest, and salt, stirring well.
Cumin Black Beans
Rinse and drain your cans of black beans. (If using homemade, make about 3 cups).
Add beans, salt, and spices to a small saucepot. Cook over medium-low heat for about 10 minutes, stirring, until hot and softened.
Alternatively, you can use plain black beans or chickpeas in this recipe if you'd like.
Avocado Sauce
Remove the ribs and seeds from the jalapeño (or keep them if you like extra spice!).
Add all avocado sauce ingredients to a blender, and blend on high until smooth and creamy.
Putting It All Together
Assemble your bowls. Add on a layer of baby kale or spinach, if desired. Layer on the black beans and rice, then add on cauliflower. Drizzle everything with the avocado sauce, and top with chopped green onions and jalapeños (if you'd like). Add on some hot sauce or extra black pepper, if you'd like.
