Prep the ingredients: Chop the scallions, keeping the whites and greens separate. Mince the garlic. Drain and rinse the beans. Core, seed, and remove the white veins from the poblano, then dice into 1/2-inch cubes. Halve, peel and dice the onion.

Brown the beef: Heat a drizzle of oil in a large pan over medium–high heat. Add the ground beef and cook, breaking up the pieces, for about 5-6 minutes, or until golden brown and no longer pink. Season with salt and pepper and set aside.

Cook the vegetables: Add the scallion whites, poblano, onion, and garlic to the pan. Cook, tossing, for about 6 minutes, or until slightly softened. Add chili powder and cumin and cook, stirring, for 30 seconds. Season with salt and pepper.

Simmer the chili: Add the stock concentrate, beans, crushed tomatoes, and 1 cup water to the pan. Bring to a boil, then reduce to a simmer and cook for about 10 minutes, or until thickened. Season with salt and pepper. TIP: If you have time, keep it simmering on the stove for longer! It gets better the longer it cooks.

Plate: Serve the chili divided between bowls with a sprinkle of cheddar cheese, the scallion greens, and a dollop of sour cream!
