Preheat oven to 350 degrees
Place the ground turkey into a medium skillet and add the leeks, then cook over medium-high heat until the meat is browned and leeks are soft and transparent. Drain any excess grease
Add the cardamom, cinnamon, and salt. Mix well, turn off the heat, and set aside
Roast the sweet potatoes in the oven at 400 degrees for 35-40 minutes OR use a knife to spear small slits in the sweet potatoes and microwave for 7-8 minutes, until softened
Remove the sweet potatoes from the oven or microwave and slice open. Let cool slightly
Crack the eggs in a medium bowl and whisk until the yolks and whites are well combined
Grab 7 half pint sized (8oz) mason jars then begin to layer the components. First add a large spoonful of sweet potato to the bottom, flattening the mash out so it’s spread evenly. Next, add 3 heaping spoonfuls of the ground turkey, packing slightly
Use a 1/4 measuring cup to scoop out 1/4 cup of the eggs and pour into the mason jars, then top with 4 sliced mushrooms, covering the egg completely
Add another spoonful of mashed sweet potatoes to top and flatten slightly
Place the mason jars into the oven (putting them on a sturdy baking sheet will help to avoid any spills) and bake for 20-25 minutes, until the egg is fully cooked
Let cool, screw the tops on the mason jars, and store in the refrigerator if desired. When ready to eat, move the lid and microwave for 1-2 minutes until warmed throughout
