Grilled Portobello Mushroom Caps are stuffed with tomato, ham, and cheese. Makes a great starter or meal highlighting the simplicity of grilled veggies.
Perfectly seasoned and grilled to perfection. Savory, rich, and earthy. The harmony of taste and texture explodes with flavour. An open-faced mushroom burger perfect for summer.

I love the meaty texture of portobello mushrooms. They make a great alternative to meat. Sturdy enough to use as a base in salad stacks, or even as a bun for burgers.
Grilled, sautéed, baked, or just raw on a salad, there are numerous delicious ways to incorporate mushrooms into your meals.
- Mushroom pate is a great appetizer, and they are always fun to stuff too.
- Pierogies always need a great mushroom dill sauce. So do gnocchi.
- These baked lamb rolls incorporate mushrooms in the filling to help stretch your grocery dollar.
- Cream of mushroom soup is the ultimate comfort food.

Portobello mushrooms on the bbq are so delicious. Did you know they are actually just a mature version of crimini mushrooms? I have not found a mushroom variety I did not like.
