Why can’t I phuking find watercress here in Canada? 🥔😡

And be honest with me, is arugula the NA version of it? 🥔😡 They taste similar but look different and are not exactly the same. How the phuk am I supposed to eat falafel without watercress. I made homemade falafel 🧆 and bread 🥖 and will settle for arugula 🥔🥺 💔
