Start by spiralizing your zucchini, then start boiling some water in a pot that you have a steam attachment for. When the water is boiling, place the zucchini in the steamer attachment and cover. Steam for 5 – 10 minutes and then set aside. The zucchini should be fork tender.

Meanwhile, in a cast-iron skillet, cook your bacon until it is done to your preference. Set aside. Drain the grease but leave 1 tbsp remaining in the pan. Add the onion to the pan and saute for 5 minutes until soft. Add the tomatoes and cook until they begin to soften for another 5 minutes.

Add the spinach and saute until they have cooked down for about 1 minute. Turn off the element.

In a separate bowl, whisk the egg yolk, coconut milk, and salt. Add the hot zucchini noodles to the skillet, and then this sauce. Stir to fully incorporate everything. The pan will be hot enough to cook this sauce even though it is turned off. Serve immediately.
