Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Toss the cubed sweet potatoes with half of the avocado oil and a pinch of sea salt, then spread them in a single layer on the baking sheet.
Roast the sweet potatoes for 20-25 minutes, flipping halfway through, until they are tender and the edges are golden brown.
While the potatoes roast, season the sirloin steak with salt and pepper.
Heat the remaining avocado oil in a cast-iron skillet over medium-high heat and sear the steak for 3-4 minutes per side for medium-rare, then remove from the pan and let it rest for 5 minutes before slicing into strips.
In a small bowl, whisk the eggs thoroughly.
Lower the skillet heat to medium-low and pour in the eggs, stirring gently with a spatula until they are just set and fluffy.
Plate the scrambled eggs alongside the sliced steak and roasted sweet potatoes for a balanced, high-protein breakfast.
