basil pesto agnolotti -- suggestion on simple sauce (well intentioned but not such a hot cook) thnks!

I agree with BlissfulBaker; some butter and parmesan would suffice.

That sounds flavorful enough to need very little in the way of sauce. You can simply toss them with some melted butter (or olive oil) and freshly grated parmesan cheese. Yum! If you definitely want a sauce, here's an easy one, and I like the combined flavors of pesto & tomatoes: http://www.food52.com/blog/2380_marcella_hazans_tomato_sauce_with_onion_and_butter
