From here it's just a matter of tossing all the other ingredients together.
In a large bowl, add the orzo and pesto and toss until the pasta is coated with the latter. Add the veggie and shrimp mixture and stir to combine. Add more pesto sauce if you feel it needs more flavor. I like to drizzle mine with a little extra olive oil and about 1 tablespoon lemon juice right before serving.
This will serve 2-3 as a main course and more as a side (can omit the shrimp if serving as a side dish).
