I made two because I got too much burger.
Then I asked the baker at Underground Bakery (the only European style bakerie I've found in the US) if he'd make me a couple of hamburger buns, not a staple in his inventory. He agreed, and did a tray of them today. I got two.
I think they'll be good, though in the past Hatch chilies have occasionally surprised me, and caused my stomach to wonder what the hell my mouth was doing. So we'll see.
