Check it out below:
800 g baby new potatoes, 500 g oyster mushrooms, 500 g green asparagus, ½ dl olive oil, salt, pepper, marjoram
Clean and halve the asparagus. Parboil them in salted water until almost tender. Boil the potatoes in their skins in salted water, then peel them. Cut off the mushroom caps. In a large skillet (or casserole dish), place the cooked new potatoes, sprinkle with asparagus pieces, and finally the mushroom caps. Drizzle olive oil over the vegetables, then season with salt, pepper, and marjoram. Bake at 180°C for 25-30 minutes. Towards the end, the mushroom caps will turn golden brown.
In the last 10-15 minutes, you can sprinkle some diced feta cheese on top of the vegetables to enrich their flavor even more.
