Alfredo Primavera Oct 1, 2009 Feel free to substitute whatever vegetables are in season and freshest in your market when preparing this super-simple pasta dinner. Though, when I was sautéing the veggies, I was seriously worried that I had managed to outdo myself and the pasta:veggie ratio would end up like 1:4. While this sauce is primarily for a pasta primavera dish, it also goes great as a substitute for marinara sauce. Pasta Primavera isn’t just for spring and summer, this is a veggie packed pasta dish that’s perfect year round!It has such a satisfying flavor and it’s versatile recipe so you can add different kinds of vegetables you might already have on hand. I like my primavera with a white sauce and tons of vegetables…you know me, any excuse to add another veggie is one well worth it. This pasta primavera sauce is a delicious tomato base with fresh vegetables, herbs, and spices. Put it on a pizza, lasagna, or even bake it over cheese filled manicotti shells!
