If your chorizo came in links with a casing, cut down the center of each sausage link and remove the casing.
Crack the eggs in a bowl and add the milk, kosher salt, and pepper. Whisk until combined.
Preheat the griddle to medium heat and add the ground chorizo on one side. Break it apart with hibachi spatulas, which does take a minute or two.
Add some cooking oil to the other side of the griddle and slowly pour the eggs, stopping a few times to use the hibachi spatulas to keep it contained so it doesn't go all over the griddle.
Flip the sausage a few times as it cooks and scramble the eggs. Remove once the sausage is cooked and eggs are cooked how you like, about 3 to 5 minutes total.Note: My flour tortillas were uncooked so I cooked them on the griddle a minute per side. If yours are cooked just skip this step.
Turn the griddle off so the chorizo and eggs can cool and time for you to make the burritos. To assemble each burrito, cut a slice of pepper jack cheese in half and place in the center of each tortilla. Add some egg, sausage, a drizzle of maple syrup and/ or hot sauce if using. Fold the sides in and tightly roll into a burrito.
Place the burritos seam side down on a tray and preheat the griddle to medium. Add some cooking oil, place the burritos seam side down and cook them 1 1/2 to 2 minutes per side.
Put the burritos back on the tray and serve. These can also be wrapped in foil and stored in the freezer. Remove the foil and heat them for a minute or two in the microwave.
