Vegetarian Collard Greens with Shiitake Mushrooms

Combine broth, paprika, cumin, salt, and crushed red pepper in a small saucepan; bring to a simmer. Cook for 1 minute. Set aside and keep warm.

Heat oil in a large pot over medium-high heat. Add mushrooms and garlic; cook, stirring frequently, until browned and tender, 4 to 6 minutes. Add 2 Tbsp. of the broth mixture to the pan and cook, scraping the bottom of the pan to loosen any browned bits, for 1 minute more.

Stir in collard greens, a few handfuls at a time. Cook, stirring frequently and gradually adding the broth mixture, a few tablespoons at a time, until the greens are tender and the broth mixture is incorporated, about 10 minutes. Reduce heat to medium if the mixture starts to boil too vigorously.

Stir in vinegar, hot sauce, and pepper; cook for 1 minute.
