Heat a non-stick skillet over medium heat and add half of the avocado oil.
Place the turkey bacon slices in the skillet and cook until they reach your desired level of crispiness, then set aside on a paper towel.
In the same skillet, add the baby spinach and a pinch of salt, sautéing for 1-2 minutes until just wilted, then remove from the pan.
Wipe the skillet if necessary, add the remaining oil, and pour in the liquid egg whites. Cook undisturbed until the edges set, then fold into a square shape that fits the muffin.
While the eggs finish cooking, split and toast the sprouted grain English muffin until golden brown.
Spread the goat cheese onto the bottom half of the toasted muffin.
Layer the cooked egg white patty, sautéed spinach, crispy turkey bacon, and sliced avocado on top.
Close the sandwich with the other muffin half and serve immediately while warm.
