Poke sweetpotatoes with a fork, place on a plate, and cover with a damp paper towel. Microwave for 5-6 minutes, or until mostly tender. Let cool for a few minutes, then dice into small chunks, about ½-inch to 1-inch each (leave the skin on; it adds fiber).
Meanwhile, crack the eggs into a mixing bowl. Add the milk and whisk until well combined. Set aside for now.
Heat 1 ½ tablespoons of olive oil in a skillet over medium heat. Add the sweetpotatoes and season with salt and pepper. Cook for about 5-7 minutes, stirring occasionally, until fully tender and browned a bit on the outside.
Add the spinach to the skillet and cook for about 2-3 minutes, stirring often, until wilted. (You may have to work in two batches depending on the size of your skillet). Pour the sweetpotatoes and spinach into a large bowl.
Heat the remaining ½ tablespoon of olive oil in the same skillet over medium-low heat. Add the whisked eggs and the sun-dried tomatoes. Cook for about 2-4 minutes, stirring often, until the scrambled eggs are cooked through. Pour into the bowl with the sweetpotatoes and spinach.
Add the roasted red peppers to the bowl. Stir all the ingredients together until well combined.
Lay out the spinach herb wraps. Portion 2 tablespoons of feta cheese into each wrap. Divide the sweetpotato/veggie/egg mixture evenly between all the wraps.
Roll the burritos. If enjoying now, dig in! If freezing, wrap each burrito in plastic wrap and then either place in a ziptop bag or wrap again in foil. Freeze for up to 3 months. When ready to enjoy, remove from the bag or foil, remove the plastic wrap, and microwave for 2 ½ to 3 minutes, until hot throughout.
