Tired bees seem to come and rest on the flowers in the herb spiral: I can’t decide if it’s because it’s warm near the bricks, or because there are a tonne of tiny thyme flowers within crawling distance.
Zest the lemon, reserving the juice for later. Combine the zest, thyme and enough olive oil to make the mixture pourable in a bowl. Clean and slice the mushrooms and place them in a single layer on a baking sheet. Drizzle with half the olive oil mixture and season with salt and pepper.
Bake for 10 minutes. Sprinkle the parma over the mushrooms and return to the oven for another 5 minutes, or until the cheese is lovely and golden.Drizzle the remaining olive oil mixture and some lemon juice (to taste) over the mushrooms.
