Stuffed Mushrooms - The Collagen Co.

These Stuffed Mushrooms are a quick, flavour-packed meal for one — juicy portobello caps filled with a rich tomato, pesto and garlic mix, topped with salty feta and a golden almond crunch. Baked (or air-fried) until perfectly melty, they’re best enjoyed alongside a refreshing glass of mixed berry collagen for an easy high-protein boost.

Serves 1

Ingredients

  • 3 large portobello mushrooms
  • 1/2 can chopped tomatoes
  • 1 tsp pesto
  • 1 tsp garlic paste
  • 45 g feta cheese
  • 1 tbsp almond meal
  • Olive oil spray
  • 1 serve mixed berry collagen

Method

  1. Remove the stalks from the mushrooms and finely dice them. Add to a bowl with the chopped tomatoes, pesto, and garlic paste. Stir until well combined.

  2. Lightly spray both sides of the mushroom caps with olive oil. Place on a baking tray and fill each mushroom with the tomato mixture.

  3. Top with feta cheese, then sprinkle with almond meal.

  4. Bake or air-fry at 170°C for 15 minutes, or until lightly golden.

  5. Add the berry collagen to a glass of cold water, stir to dissolve, and enjoy on the side.
