300g chestnut mushrooms, halved if small, quartered if large
3 tbsp olive oil, reserving one 1 tbsp for brushing
1/2 small red onion, chopped
1 small leek finely sliced
100g spinach
Salt and pepper to taste
4 slices crusty bread
150g parmesan, finely grated
5 large eggs
130ml milk
Method
Brush one tablespoon of oil into a 12 inch oven safe pan (or a 9×13 baking dish).
Heat olive oil in a large skillet over medium-high heat. Stir in the onions and cook until softened, about 5 minutes. Add in the mushrooms and leeks and cook until they are softened, about 3 minutes. Stir in the spinach and cook until wilted, about 1 minute. Remove from heat and set aside to cool.
Arrange bread slices in a single layer in the skillet. Layer bread with mushroom mixture. Crack the eggs on top. Season with salt and pepper. Pour milk evenly over top and sprinkle with the cheese. Bake until the eggs are set, about 25-30 minutes.
