Vegetable

You can substitute fresh or frozen peas for the fava beans. Drain the ricotta in a sieve set over a bowl for about 10 minutes to remove excess liquid. Try to find the denser buffalo ricotta for this recipe. If you use regular ricotta, the filling won’t be as thick.

The pesto can be made up to 1 hour before serving without losing its freshness; store it at room temperature.

You can substitute any variety of ripe tomato for the heirlooms called for here.
