These are perfect as an appetizer or even a nutritious vegetarian entree

In our opinion, the combination of fresh tomatoes, creamy mozzarella, and tangy basil in a traditional Caprese salad can’t be topped! Except, maybe, by putting it all in a portobello mushroom. That’s why we made these Caprese Stuffed Portobello Mushrooms! By using part-skim mozzarella and skipping the dressing, you’ll get all the delicious flavors of a Caprese salad with only a fraction of the calories.

These are perfect as an appetizer or even a nutritious vegetarian entree. Drizzle with some balsamic vinegar upon presentation to add a tangy pop!
