Cut the bacon slices in half, leave them crisp in a frying pan and set aside. Wash, clean and slice the mushrooms. Clean and wash spring onions and cut them into rings.
Fry the mushrooms and 2/3 of the spring onions in the bacon fat and season with salt and pepper. Wash, clean and slice the tomatoes. Cover four slices of toast bread with tomatoes, steamed vegetables and a slice of Gouda each.
For the rest of the toasts, cut the peach halves into fans and the bresso into slices. Toasts alternate with cooked ham, peach and bresso. Bake in a preheated oven (electric: 225°C/ gas: level 4) for five minutes.
Add the bacon and remaining spring onion rings. Serve garnished with fresh herbs.
