About 10-15 minutes before serving, add in asparagus (I like mine with some crunch, add it earlier if you want it softer), spinach, peas and pasta. Cook on low for another 10-15 minutes then stir in grated cheese. Taste and season with salt and pepper as desired. I used about a 1/2 teaspoon of each, but it will depend on the sodium levels in your stock, tomatoes, etc. Serve immediately with additional cheese on top!
