Cook the chorizo in a skillet over medium heat for 7 to 8 minutes until browned and 160°F, then drain excess fat.
Mash half the black beans and stir all the beans into the chorizo.
Whisk the eggs with salt, add them to the skillet and stir until set to 160°F.
Cool the filling completely and divide it among the tortillas with the Monterey Jack.
Roll tightly, toast seam-side down for 1 minute, cool again, wrap in parchment and foil, and freeze for up to 2 months.
Remove the foil and microwave in parchment for 2 to 3 minutes, turning once, until the center reaches 165°F.
