Organic Girl Romaine Mix Salad... omg EWW

i purchased this salad today cause i always wanted to try it. it has pretty packaging and claims to have been washed 3x so you don't have to. i took the first bite of the salad and notice this bitter, limey taste an then started digging around the leaves for the culpret. i found it to be this four leaf clover long looking thing and i ended up picking it all out! what do you guys thing this was? has anyone else ate this and liked it? i'm almost wondering if it was a mint leaf? i wanna gag thinking about eating it. just... bad.

oh and then after that, i heard my puppy chewing on the couch so i grabbed some bitter yuck to spray and it turns out i got it on my hand, then picked up my egg sandwich. what an appetite killer. i am NOT having a good food day!
