Hatch Chile Sloppy Joes (Hatchy Joes) are sloppy joes made with Hatch chiles. They're slightly spicy and slightly sweet, and a real crowd pleaser.
In a large heavy pot, heat the olive oil on medium heat, and add the onions. Saute until translucent. Add the Hatch chile peppers and continue sauteeing for another two minutes. Remove peppers and onions from the pot and set aside.
Brown the ground beef (or ground beef substitute) in the pot until cooked through. Pour off any remaining grease.
In a medium bowl, whisk together the Hatch chile ketchup, brown sugar, tomato paste, chile powder, and water. Pour over the ground beef and add the pepper-onion mixture back to the pot as well. Stir to combine. Simmer over low heat for 20 minutes. If mixture gets too thick, add additional water until the mixture reaches the desired (loose) consistency.
Spoon mixture onto hamburger buns and serve.
