Start by cooking the quinoa: rinse ¾ cup quinoa well, then combine with 1½ cups vegetable broth in a small pot. Bring to boil, reduce to low, cover and simmer 10–11 minutes (slightly underdone is perfect). Fluff and set aside uncovered to cool slightly.

Preheat oven to 390°F (200°C) and line a large baking sheet with parchment. Remove stems from mushrooms and scrape out dark gills completely with a spoon (this prevents grey filling). Lightly brush caps with a little oil.

Place mushrooms gill-side DOWN on the sheet and bake 10 minutes. This step is crucial — you’ll see liquid pool underneath.

While mushrooms bake, massage the kale: put chopped kale in a large bowl with lemon juice, zest, and ½ tsp salt. Massage firmly with clean hands for 60–90 seconds until it turns dark green and silky. Magic!

Add cooled quinoa, chopped sun-dried tomatoes, toasted pine nuts, minced garlic, ⅔ cup feta, 3 tbsp tomato oil, black pepper, and any remaining lemon juice to the kale. Mix thoroughly — taste and adjust salt (feta is salty).

Remove mushrooms from oven. Carefully flip them, pour off all collected liquid, and pat insides dry with paper towel. Your mushroom bowls are now ready and won’t water down the filling!

Spoon a generous 1½–2 tablespoons of the quinoa-kale mixture into each cap, pressing gently and mounding high — these shrink a bit, so overfill slightly.

Crumble the remaining ⅓ cup feta over the tops (this creates gorgeous melty pockets). Lightly press so it sticks.

Bake 12–14 minutes until mushrooms are tender and filling is hot. Switch oven to BROIL (high) for 1–2 minutes until feta turns golden in spots — watch like a hawk!

Rest 8 minutes (filling stays piping hot), then arrange on a platter, scatter a few extra pine nuts and feta crumbles, add lemon wedges for squeezing, and serve warm or room temperature. Prepare for “I can’t believe this is healthy” comments!
