1
Grease a 9 x 13 glass baking dish.
-
2
Preheat your broiler.
-
3
My oven currently only has one temperature for this (or maybe I just dont know how to use it properly).
-
4
Put an oven rack on the highest shelf so that it is close to the broiler unit.
-
5
Put your poblano peppers on a baking sheet, and put them in the oven on the top rack.
-
6
Keep an eye on them while they broil.
-
7
I usually rotate them around every 5-6 minutes to make sure they are getting evenly blackened on all sides.
-
8
Once they are good, black and roasted, remove them from the oven and put them in a plastic or paper bag.
-
9
Seal them up and let them sit for about 15 minutes.
-
10
Set the oven to 350 F.
-
11
When the peppers have finished steaming, remove the skins, stems and seeds.
-
12
Dont worry if they fall apart a little or if some of the seeds remain.
-
13
In a skillet over medium heat, cook the ground beef and onions until the ground beef is no longer pink.
-
14
Drain off fat and return the skillet to the stove.
-
15
Add the tomato sauce and spices (cumin through salt) to the cooked meat and stir to combine together.
-
16
Whisk together the egg whites, milk and flour in a bowl.
-
17
Pour half of the mixture into the prepared baking dish.
-
18
Arrange the half the poblanos in the dish, top with half of the meat mixture, and half of the shredded cheese.
-
19
Add another layer of poblanos, the rest of the meat and the remaining egg white mixture.
-
20
Then top with the remaining shredded cheese.
-
21
Bake for 45-50 minutes until the egg mixture has set.
-
22
Remove from the oven and let it cool for a few minutes.
-
23
Serve with all of your favorite Mexican food toppings, sour cream, salsa, etc.
