Prepare the pasta as instructed on package. Pour the peas into the pot with the pasta to boil for the last 5 minutes of cooking. Drain both and place back into the pot.
In a blender or food processor, blend together all of the pesto ingredients. For a creamier texture, add more olive oil by the tablespoon.
Once fully blended, mix the pesto in with the pasta and peas. Pour in the tomatoes and olives and stir together.
Top with crushed black pepper and fresh basil leaves!
Leftover pesto will last in the fridge for up to 1 week, or freezer for up to 1 month.
