A new twist on a traditional basil pesto, the arugula gives it a refreshingly sharp bite that compliments the richness of the parmesan and lends itself well to al dente pasta and fresh veggies.
Bring a pot of water to a boil. Add in the pasta, stir and cook to aldente. Drain pasta and toss with a little oil so it doesn't stick. Add in the onion, and tomatoes.
For the pesto pulse arugula, garlic, walnuts, salt, pepper, parmesan and some of the oil in a food processor. Add more oil as needed to combine it all and create a sauce like consistency.
Toss pasta and veggies with the pesto. Toss in the left over arugula. Adjust seasoning if needed.
