Aug is the start of New Mexico Hatch chili season! My go to spot for Hatch chilies, though many places sell it... Food City sells the 1 bushel bags (~25-30lbs) in mild/medhot/hot or already roasted outside in the parking lot. No guessing, wondering what you're getting. If you buy bushels such as I, let the cashier know so they will charge you appropriately (10cents more per lb) and the guy outside will roast for you w/ receipt. Roasting at home is a long and tedious process when you're talking 30-60 lbs of chilies on a normal grill. I personally like to mix a bag of mild and medium to freeze for an entire year of green chili goodness.
Don't forget to pickup the cojita cheese and crema as well, apparently Food City is award winning for their corn and flour tortillas which this location does make on site. Sometimes I purchase some of their watery fresh fruit juices if it's avail as I walk in.
Worst case if the chilies are out, you can go across the street for already roasted and bagged (about double in price) but you don't know what spice level chili you're buying.. so ask if you can sample.
