Just like the lightbulb or zip-close bag, the slow cooker is one invention we can’t live without. There’s no lack of flavor when harmonious ingredients sit together cooking happily for hours without fuss. Case in point? This crowd-pleasing beef and black bean chili, packed with scallions, garlic, tomatoes, and all the quintessential spices. Serve this big batch meal to your hungry crowd with toppings galore, like scallion greens, tortilla chips, smoky red pepper crema, and cheddar cheese. This recipe is double the typical servings, providing 4 servings and 8 servings for a 2 person and 4 person box respectively.
