I feel like red sauce is a little heavy for when the weather is nice so I like to go another way.
You can use any kind of cheese you want if you don't want to do the 1/2 sawdust grated parmesan that's fine. I like sawdust, it's what turns boys into men. I bet Ron Swanson eats sawdust and his mustache is better than yours. Oh, you don't have a mustache or what one you say, eat some sawdust and man up Nancy boy.
Also, salt the water for the pasta if you want. I don't because I'm a rebel and I like to live on the edge. It's anarchy but I play by my own set of rules.
