Making:
Cook the mortadella and pistachio ravioli in boiling water, then prepare a pistachio pesto using pistachio, parmesan, a clove of garlic, salt and milk.
Blend everything until the pesto is thick and fluid. At this point, melt the butter in a pan over moderate heat (25 g of butter for every 100 g of pasta). For flavor you can also add some breadcrumbs.
Once the butter has melted, transfer the ravioli to the pan and add a little pesto and grated Parmesan while cooking.
Finally, plate the ravioli by adding more pesto, pecorino, a little pepper and some lemon zest.
The ravioli are ready, you just have to taste them!
