Chiles Rellenos is a classic Mexican dish that consists of roasted poblano peppers stuffed with cheese or meat, dipped in egg batter, and fried until golden and crispy. The peppers are first roasted to remove the skin, then carefully slit open to remove the seeds and veins. Stuff the peppers with your choice of cheese, such as Oaxaca or Monterey Jack, or ground meat like beef or chicken. Dip the stuffed peppers in a light egg batter and fry them until they are golden brown. Serve the Chiles Rellenos with a tomato-based sauce and garnish with fresh cilantro and sour cream.
