These vegan stuffed mushrooms are big portobello caps filled with a Greek-style stuffing of roasted red peppers, spinach, crispy panko and tangy vegan feta. Serve them as a hearty vegan main or halve them for an easy holiday side.
Gently clean the mushroom caps with a damp paper towel. Use a spoon to remove the stem and gills from the underside of the mushrooms.
Spray the mushroom caps with olive oil spray on both sides and sprinkle generously with salt and pepper. Place them stem side up on a baking sheet.
Heat 1 tablespoon olive oil in a large nonstick pan over medium heat. Add the onion and cook for 3-4 minutes, until softened. Add the roasted red peppers, garlic, oregano and dill and cook for 2-3 minutes more.
Add the spinach and cook until wilted, about 2-3 minutes. Stir in the panko and the vegan feta (if using) and cook for 1-2 minutes, until heated through. Remove from the heat.
Spoon the filling into the four mushroom caps, mounding it up. Bake for 20-25 minutes, until the mushrooms are tender and the tops are lightly browned. Sprinkle with chopped fresh parsley and add a squeeze of lemon just before serving, if you like.

Notes
Cleaning: wipe the mushrooms with a damp paper towel rather than rinsing them, so they don't get soggy.Make ahead: the filling keeps, covered, in the fridge for up to 2 days. Stuff the caps and bake as directed, adding 3 to 5 minutes for the cold filling. You can also stuff the mushrooms a few hours ahead and refrigerate them until baking.Appetizer size: use about 24 cremini or white button mushrooms and bake for 15 to 18 minutes.Storage: refrigerate leftovers in an airtight container for up to 3 days and reheat at 350°F for about 10 minutes. Baked mushrooms don't freeze well, but the filling freezes for up to 2 months.Vegan feta: use homemade vegan feta or a store-bought block, or leave it out and finish with a squeeze of lemon.
