Since arugula is basically a spring green perhaps the southern sun isn’t as hot on your balcony at this time of year? Maybe try it next year. I had great success with it and even the deer didn’t find it. Otherwise, the stuff in the supermarkets is fine.
I’m going to make a fennel and orange salad over Arugula this week. I saw an Extra Virgin episode in which it was put into a hero roll with a hot pork sausage! Since I’m dieting, no sausage meat for me. But it looked to die for.
Try a bahn mi sangwich, it wont kill ya ;)
