How it's done Heat a little oil in a frying pan and heat the Lazy Vegan Gnocchi al Pesto Rosso for 8-10 min. Place the Gnocchi al Pesto Rosso in an oven dish and cover with the vegan Parmesan cheese. Place the baking dish in a preheated oven at 190 degrees and heat the dish for about 15 minutes until the top layer is crispy and golden brown. Top the dish with some basil leaves. Enjoy!
