A favourite way using rigatoni from ” River Cafe Cook Book Easy” by Rose Gray and Ruth Rogers. Gruyere cheese can be substituted for the Fontina but the latter will melt easily and have a rich buttery taste.
Another recipe from The Greens Cookbook and a great way to use courgettes in summer when they are plentiful. It’s beautifully light and my go to courgette frittata. It takes a bit longer than average but if there are two of you it will do for 2 or 3 days, and it also works well as part of a vegetarian spread for entertaining. If you can find Scamorza cheese i recommend using it.
