4 Portobello mushroom caps
3 tablespoons extra virgin olive oil
3 tablespoons balsamic vinegar
Kosher or sea salt and black pepper
2 cups chopped fresh (preferably organic) spinach (about 2 ounces)
1 cup crumbled soft goat cheese, or Greek feta cheese (your preference)
Pre‐heat oven to 450 degrees
Leeks are sandy by nature. Their flavor is well worth the preparation. Here’s an easy way to clean them.
1) Trim dark‐green parts from leeks; slice leeks crosswise, and soak in cold water. Swish leeks to help loosen dirt. Repeat with fresh water until you no longer see any grit at bottom of bowl. Lift leek slices out of water, leaving grit behind; drain them thoroughly on paper towels.
2) Place mushroom caps, gill sides up, on a rimmed baking sheet; drizzle with oil and vinegar, and season with salt and pepper. Bake until caps are just tender, about 20 - 25 minutes.
3) Top with leeks, spinach, and cheese; season again if desired.
4) Bake until spinach wilts and cheese starts to brown, 10 to 12 minutes.
