Breakfast tacos with grilled chuck and fried egg

Mix about a quarter cup of green salsa with 2 or 3 tablespoons of sour cream, a little cayenne, a squeeze of lime juice and a tiny bit of salt.

Fry an egg in a little butter, keeping the yolk unbroken; season with salt and pepper.

Warm the corn tortilla until marked.

Spread the sauce on the tortilla, add the egg and sliced chuck, then avocado, fresh radish, a little Cotija and chopped cilantro; the yolk bursts as it is folded.
