Browned Butter Pasta with Tatsoi

Your pasta of choice, preferably curved or with ridges
1/2 stick unsalted butter
Salt and pepper
Leaves of 1-2 bunches of tatsoi, rinsed
1/2 cup chopped thyme
Freshly grated parmesan
Lemon wedges, optional
Cook pasta to al dente in salted water.
When pasta is almost done, melt butter in a skillet. Swirl the butter in the pan as it foams. (At this point, remove pasta from the heat and drain well in a colander.) When butter begins to brown, toss in pasta and mix to coat with butter. Salt and pepper to taste. Add tatsoi and thyme and cook until slightly wilted, about 1 to 2 minutes. Plate and serve immediately with grated Parmesan and lemon wedges on the side.
