Mexican Pickled Red Onions

“I’ve experimented a bit with pickled red onions. As I love Mexican food, this variation was a must. This recipe is not sweet like my other pickled onion recipe and is rich with oregano. If you are using this on Mexican food, make sure you use Mexican oregano (found in bags the Hispanic food aisle) as the flavor is much different than Italian or Greek oregano. You could certainly make this recipe with these other oreganos if you are using the pickled onions on other things.” – April Ferre
