Preheat your oven to 400°F (200°C).
Roast the poblano peppers on a baking sheet until the skin blisters.
Remove the peppers and place them in a plastic bag for 10 minutes to steam.
Peel the skin off the peppers carefully.
Cut a slit in each pepper and remove the seeds.
In a bowl, mix cheese and ground meat (if using).
Stuff each pepper with the filling.
In a separate bowl, beat the eggs until fluffy.
Add flour, salt, pepper, and cumin to the egg mixture.
Dip each stuffed pepper into the batter and fry in hot oil until golden brown.
