Yes, Get you a Mexican woman to make them for you.
Seriously, if you're used to really good authentic, then no, not an easy way. Its time consuming.
I wouldnt But, you can....
Use canned chilies and canned tomatoes instead of fresh and roasted. Won't be the same though.
The batter and sauce are key. Chupa taught me a trick for the sauce. Roasted tortilla for flavor and texture, its puréed with the tomatoes. Boon!
so not authentic after all ?
I'll incorporate eggs in my Rellenos to satisfy R-n and Hm-n.
H, rellenos are roasted and pealed poblano peppers, stuffed with Queso Chihuahua or other cheese, some other ingredients are sometimes used too. Then battered in egg and pan fried. Then topped with most commonly, a roasted tomato sauce.
