1⁄2 cup plain non-dairy creamer or half and half cream (10%)
3⁄4 cup grated mozzarella cheese
Preheat oven to 425° F. Line Sheet Pan with Sheet Pan Liner. Using a spoon, scrape out mushroom gills (save these for the sauce!).
Brush mushroom caps with oil and season with salt and pepper. Place on pan; bake until tender, 12–15 min.
Meanwhile, in large Multipurpose Pot, combine mix with tomatoes, water, and creamer. Add mushroom gills. Cover; simmer on medium heat for 15 min, stirring occasionally. Taste, then season with salt and pepper.
Once mushrooms are tender, pour out liquid, if desired. Scoop sauce into each mushroom cap and top with cheese. Bake until cheese is melted, about 2–3 min.
