Preheat the oven to 400°F (200°C).
Roast the poblano peppers over an open flame or in the oven until the skin is charred.
Place the charred peppers in a plastic bag for about 10 minutes to steam.
Peel the skin off the peppers carefully.
Make a slit in each pepper and remove the seeds.
In a bowl, mix shredded cheese, cooked meat, and beans.
Stuff each pepper with the cheese mixture.
In a separate bowl, beat the eggs until frothy.
Dredge the stuffed peppers in flour, then dip them in the beaten eggs.
Heat oil in a pan and fry the peppers until golden brown on all sides.
Serve hot with tomato sauce drizzled over the top.
