Peel the onion(s), slice in half and make vertical slices on both onions halves
On medium heat melt and coat the bottom of a shallow skillet with the dairy free butter and oil.
Add your onions to the pan and proceed to saute them
Evenly distribute the onions in the pan and let them sit for a few minutes before stirring them again. If your stove top cooks quite hot then you may need to adjust the heat to medium-low
After 10 minutes, sprinkle in some pink salt and a splash of browning (if you are using it).
Let the onions cook for about 40 minutes or until they take on a rich brown hue, stirring every few minutes allowing the onions to stick a little so they brown and using a spatula to scrape off that caramelization. If the onions seems like they are burning then replenish with a splash of water and repeat this cycle.
Once the onions have caramelized add the tomatoes, thyme leaves, black pepper, hot sauce.
Let the onions cook down further for another 5-10 minutes
