Healthy Lentil Chili

1 tablespoon olive oil

1 large onion, diced

1 red, orange or yellow bell pepper, diced

4 cloves garlic, minced

Kosher salt and freshly ground black pepper

2 tablespoons tomato paste

2 tablespoons chili powder

1 1/2 teaspoons dried oregano

1/2 teaspoon ground cumin

4 cups low-sodium vegetable broth

Two 14.5-ounce cans fire-roasted diced tomatoes

One 15-ounce can navy beans or another small white bean (do not drain)

1 cup dried brown lentils

1 dried bay leaf

1 tablespoon red wine vinegar

Shredded reduced-fat Cheddar, plain yogurt, pickled jalapenos and crushed tortilla chips, for serving (all are optional)

Heat the olive oil in a large pot or Dutch oven over medium-high heat until shimmering. Add the onion, bell pepper, garlic, 1/2 teaspoon salt and several grinds of black pepper. Cook until vegetables are just tender and browned in spots, stirring occasionally, about 6 minutes. Stir in the tomato paste, chili powder, oregano and cumin, then continue to cook until fragrant and brick-red in color, stirring frequently, about 2 minutes.
Stir in the chicken broth, diced tomatoes, beans (and their liquid), lentils, bay leaf, 1/2 teaspoon salt and a couple grinds of black pepper. Bring to a steady simmer, then reduce the heat to medium-low. Partially cover with a lid and gently simmer, stirring occasionally, until the lentils are tender and the chili has thickened slightly, 35 to 45 minutes.
Remove the bay leaf and stir in the vinegar. Season with salt and black pepper. Ladle into bowls and serve with toppings as desired.
