Packed with flavor from both the Pesto and all the fresh vegetables this is one wonderful summer salad! Chop all the veggies while the Pasta is cooking, then just toss it all together. Easy as pie! I used whatever vegetables I had in the fridge but you can certainly vary the recipe with what you have on hand. Green Peas, chopped Artichoke Hearts or a can of Chick Peas would be wonderful additions. I like the Queso Fresco for its texture and mild flavor but Provolone, Gouda or Swiss would also work well.
