Wash and chop vegetables and set water on to boil for the pasta.
In a large skillet or pan heat 1 tbsp olive oil (or cooking oil of choice) over medium heat add garlic and stir until fragrant. Next add all of the veggies except the frozen peas to the pan. Once water boils add the pasta.
Let the veggies cook for about 8 minutes or until mostly tender. Add frozen peas and cook until thawed and soft.
Drain cooked pasta but do not rinse.
Add 2 tbsp flour to the pan of veggies and gently toss to coat. Add milk and stir slowly over medium heat until sauce begins to thicken. This will take 10-15 minutes. Add parmesan cheese and stir until melted.
Add pasta and toss to coat. Serve pasta with extra parmesan cheese for topping.
