If you don't you could achieve a satisfactory result with the following:
1 small can of Hatch chili peppers, loosely drained
1 jalapeno pepper, seeded and diced
2 garlic cloves, minced
¼ yellow onion, minced
¼ TSP salt
Up to 1 cup chicken broth
Corn oil
Flour
Sweat the onion in 3 TBS of corn oil until translucent, about 8 minutes. Add the garlic, saute for 30 seconds more, then add 1 TBS of flour. Stir until blended and pasty; thin to a gravy with the chicken broth. Add the peppers, loosely cover and simmer for 15 minutes on low heat.
The Mayo
½ cup of Enchilada Verde sauce or the above quickie sauce
1 roasted poblano pepper, peeled and seeded
8 - 10 pickled jalapeno slices
¼ mayonnaise
In a mini food processor add the sauce, poblano and jalapeno slices. Process until smooth and nearly uniform in color and texture, about 2 minutes. Add the mayonnaise and then process an additional 30 seconds.
