Dice half an onion, mince a jalapeño, and chop a tomato. Crack 4–6 eggs into a bowl and whisk with 1/2 teaspoon salt.
Heat 1–2 tablespoons oil in a skillet over medium. Cook onion and jalapeño until softened and glossy, about 3–4 minutes. Add garlic for 30 seconds if you're feeling extra.
Stir in the tomato or a spoonful of salsa. Cook 1 minute to mellow the raw edge.
Pour in the eggs and let them set for 10–15 seconds. Nudge gently with a spatula.
Toss in a couple handfuls of tortilla chips. Fold gently so half the chips soften and half stay crunchy. That contrast? Magic.
Sprinkle cheese and let it melt. Kill the heat. Shower with cilantro, scallions, and a squeeze of lime. Hit it with hot sauce if you like chaos.
