Combine the meat, bacon, no-tomato sauce, onion, ginger, garlic powder, and oregano in a slow-cooker and cook on high for 2 hours. Meanwhile, make the tortillas.
Shred the meat and scoop it into the tortillas, then top with coleslaw, guacamole, or other toppings.
Tortillas
In a large bowl, combine the flour and salt, then stir in the water and oil and knead until a smooth dough forms.
Divide the dough into six equal-sized balls and roll each one between two pieces of parchment paper to make a thin tortilla.
Heat a skillet or griddle to medium-high and cook the tortillas about 1 minute on each side, until brown spots and small air bubbles form.
