Peel the asparagus and place in a baking dish. Brush with wild garlic pesto if you like and spread thin butter flakes evenly over the top. Season with salt and pepper, spread the vegetable stock and the crumbled feta cheese evenly over the top.
Cook in the oven at 200 ° C top / bottom heat for about 30 minutes.
Baguette goes very well with it, with which you can then top up the sauce.
