Peel the white asparagus, remove the woody ends from the green asparagus, cut both into small (approx. 2 cm) pieces. Sort out the tips. Wash, core and cut the peppers into small cubes.
Heat the olive oil with a pinch of butter in a pan and lightly fry the pepper pieces. After about 1 minute add the asparagus. Season with salt and pepper. After about 2 minutes add the asparagus tips. Fry everything nice and crispy, trying now and then to see if the asparagus is good.
Pour into a bowl, drizzle some balsamic vinegar over it and serve.
Tastes warm and cold, best with grilled dishes or as an appetizer.
