Northern-style scrambled eggs vigorously mixed with shredded dried beef and chiles. This high protein, keto-friendly, carnivore dish is a fresh, hearty breakfast for family mornings.
Heat a large nonstick skillet over medium-high heat and add the vegetable oil, letting it become hot but not smoking.
Add the finely diced white onion and jalapeño, sautéing for 2-3 minutes until softened and fragrant, stirring often to prevent browning.
Stir in the shredded dried beef (machaca) and diced tomato; cook for 3-4 minutes, breaking up any clumps, allowing the machaca to sizzle and infuse flavor with the vegetables.
In a bowl, thoroughly whisk the eggs with salt and black pepper. Lower the skillet heat to medium, then pour the beaten eggs evenly over the machaca mixture.
Gently and vigorously mix the eggs into the beef with a spatula, scraping up from the pan base; cook, stirring constantly, until the eggs are just set but still moist (about 4 more minutes). Serve immediately while hot.
