Make the pesto: add the garlic to a food processor, and hit puree to chop the garlic finely.
Add the parsley, olive oil, cheese, pumpkin seed, and scallion. Puree until all the ingredients are combined into a good sauce. If needed, scrape the sides to get any parsley that didn’t get blended in and puree one more time. Set pesto aside while orzo cooks.
Cook the orzo according to package instructions. Drain, and immediately toss with the parsley pesto.
Stir in the beans, sliced olives, spinach or arugula, and the diced pepper.
Serve the orzo, passing additional cheese at the table. Enjoy!
