Delicious roasted red pepper quinoa with tangy feta cheese stuffed into a portobello mushroom — perfect as a side or a satisfying vegetarian main.

I don’t cook with mushrooms all the time, but when I do they’re a treat. My son (who polished one of these off by himself) and I love mushrooms, though my daughters aren’t as enthusiastic and my husband usually skips them. Still, I couldn’t resist combining roasted red pepper and feta — flavors I fell for in a pasta bake — with a large, meaty portobello when they were on sale. The result is a simple, flavorful dish that’s great for two or easy to scale up for more people.

This recipe makes two stuffed portobellos, which is ideal for a cozy dinner or Valentine’s Day for two. You can double or triple the ingredients if you’re cooking for a crowd. It works well as a gluten-free vegetarian main, but also pairs nicely alongside other dishes as a hearty side.

If you need a quick refresher on cooking quinoa, consult a reliable how-to guide for stove-top quinoa so you get a fluffy base for the filling. If you’re a big mushroom fan, feel free to explore other varieties and preparations to suit your taste.
Enjoy!

Instructions
- In a small pot, heat the olive oil over medium heat. Lightly sauté the minced garlic and shallot for a minute or two.

- Brush the mushroom caps with extra virgin olive oil, place them top side down on a baking sheet, and set aside.
