250 g mushrooms (cremini or button), halved or quartered
2 garlic cloves, minced
1 small shallot, finely chopped
2 tbsp chopped fresh parsley
1 tbsp chopped fresh thyme or rosemary
1 tbsp lemon juice (plus zest from ½ lemon)
Salt and freshly ground black pepper, to taste
Optional extra: 2 tbsp crumbled feta or goat cheese
Instructions
Cook pearl barley in a pot of boiling salted water until tender but still slightly chewy, about 25–30 minutes. Drain, rinse under cold water, and let cool.
Meanwhile, heat 1 tbsp olive oil and 1 tbsp butter in a skillet over medium-high heat. Add mushrooms in a single layer and sear undisturbed until golden, about 4 minutes. Flip and cook 2–3 minutes more.
