Slice zucchinis thinly or make ribbons using a mandolin or peeler for a nicer feel. Warm up olive oil in a pan over medium heat. Toss in zucchinis and cook them for about 3-4 minutes till they're soft but still have a bit of crunch.

Put your drained spaghetti into the pan with your cooked zucchinis. Stir well. Add in the pesto and mix until pasta is fully covered. If it looks dry, splash in some of that saved cooking water to help the sauce coat everything nicely.
