While most of the ingredients for this recipe are commonly found in your kitchen, you might need to pick up fresh portobello mushrooms and spinach if you don't have them on hand.

Ingredients For Grilled Stuffed Portobello Mushroom Recipe
Portobello mushrooms: Large, meaty mushrooms that serve as the base for the stuffing.
Spinach: Fresh, chopped greens that add a nutritious and vibrant element to the filling.
Feta cheese: Crumbled cheese that provides a tangy and creamy texture to the stuffing.
Olive oil: Used to mix with the stuffing and to brush on the mushrooms for grilling.
Garlic: Minced to add a robust flavor to the filling.
Salt: Enhances the overall taste of the dish.
Pepper: Adds a touch of heat and balances the flavors.
Technique Tip for This Recipe
When preparing portobello mushrooms for grilling, it's essential to clean them properly. Use a damp paper towel to gently wipe off any dirt from the mushroom caps. Avoid rinsing them under water as they can absorb moisture and become soggy. Additionally, to ensure even cooking, you can lightly score the underside of the mushroom caps with a knife, creating a crosshatch pattern. This allows the mushrooms to cook more evenly and helps the stuffing adhere better.
