In a at least a 5 quart pot, bring 4 quarts of water to a boil. Stir in 1 tablespoon of kosher salt. Add pasta, stir and cook according to the directions. You want it to be al dente when done.
Reserve 1 cup of cooking water. Drain pasta and return to pot.
Stir goat cheese mixture, remaining 1/2 cup peas and 1/4 cup of reserved pasta water into drained pasta. Stir until evenly coated, adding more cooking water 1 tablespoon at a time as needed so the sauce is creamy and clings to the pasta.
Taste and season with kosher salt and freshly pepper. Serve sprinkled with the remaining mint.
