Iron-Rich Beef and Sweet Potato Skillet

Heat half of the olive oil in a large skillet over medium heat. Add the diced sweet potatoes and cook, stirring occasionally, for about 10 to 12 minutes until fork-tender and lightly browned.

Remove the sweet potatoes from the skillet and set them aside on a plate.

In the same skillet, add the remaining olive oil over medium-high heat. Add the sliced onions and minced garlic, sautéing for 2-3 minutes until softened and aromatic.

Add the beef sirloin strips to the skillet, seasoning with salt and black pepper. Cook thoroughly, stirring frequently, until the beef is fully browned and cooked completely through with no pink remaining (well-done).

Toss the cooked sweet potatoes and baby spinach back into the skillet with the beef. Stir gently for 1-2 minutes until the spinach is wilted and everything is heated through.

Divide between plates and serve warm.
