In a small-medium soup pot or medium braiser-style pot, dry toast the cumin and coriander over medium heat until fragrant. Transfer the toasted spices to a spice grinder and grind until spices are powdered. Set aside.

Remove the stems and seeds from the poblanos and chili. Cut the peppers into rustic, 2-inch-ish pieces and place them on the baking sheet.

Place the sliced onions, tomatoes, and garlic cloves on the baking sheet as well. Toss the vegetables with the ground cumin and coriander, avocado oil, salt, and pepper. Slide the vegetables into the oven and roast for 20 minutes, or until lightly browned and uniformly soft.

Let the vegetables cool slightly before transferring to a blender or food processor. Pulse the mixture a few times until you have a chunky paste. You’re just trying to avoid large pieces of garlic and chili. Scrape this mixture into the soup pot from earlier.

Add the rice, beans, tomato paste, coconut aminos, and water to the pot. Set the pot over medium heat and bring to a boil. Lower the heat to a simmer and cover. Cook the rice and beans for 40 minutes, or until most of the liquid is absorbed and the rice is tender. Check the pot and stir every 10-15 minutes or so. Add more water if necessary.

Take the pot off the heat and let it sit for 5 minutes with the lid on. Then, remove the lid and stir in the lime juice, cilantro, and a good pinch of salt. Serve the black beans and rice hot.
