While pasta is cooking, on a separate burner add 1/2 olive oil to pan and saute vegetables (can put them on pan all together). Let saute for a few minutes and then add tomato sauce and salt/pepper. Lower heat and continue to saute for a few more mins, or until there are cooked.
Add pasta back into large pot and toss to coat pasta with remaining olive oil. Add sauted veggies into put. Add salt and pepper to taste, and enjoy!
