For New Yorkers, there's nothing like a delicious red onion sauce to go on your hot dog. But, what if you eat plant-based and avoid hot dogs like the plague? Never fear! I came up with my own recipe for the red onion sauce and it’s amazing. It’s rich, tomato-y and tangy. I can eat it out of the pot with a spoon. I can and I did. I dare say that it's even better than the one that comes from the carts and bonus points for the fact that you can put it over your favorite brand of veggie based dog.
