Erin's Parmesan-Garlic-Basil Mashed Potatoes

5 - 6 red potatoes, quartered (or cut smaller, either works), don't peel 'em.
parmesan cheese, grated, shredded, whatever (about a cup)
3 - 4 cloves chopped/pressed/minced garlic (I use way more, b/c I like garlic)
1/2 cup chopped fresh basil (I use more like a cup, I think)
1/4 cup Extra Virgin Olive Oil
sea salt & ground pepper to season/taste

Put the potatoes into a pot, cover with water plus an inch or two - bring to a boil and let cook about 15-20 mins, or until they're soft enough to coarsely mash with the side of a metal spoon. Drain, and reserve a little cooking water. Put them back in the pot on the stove, and shake a little to dry them off. Mash with the spoon, or to your desired level of mash-ness. Then dump in the garlic and olive oil - use a little reserved cooking liquid if they seem overly dry - and stir, stir, stir. Or you could use chicken/veggie stock or even milk, up to you. Next, dump in the basil and about 1/4 to 1/2 cup of parmesan, mix until everything is well combined. I'm sure I use more than that, though, maybe even a cup. Salt and pepper to taste, et voila - eat!
