Instructions: 

For the fajita subs

  • Add the water to the slow cooker. Cook the fajitas on high for 4 hours or on low for 8 hours.
  • Once cooked, turn off slow cooker and use tongs to place the mixture in a large bowl.

For the queso

  • In a medium saucepan, melt the butter over medium heat. Add the flour and continue to whisk until a roux forms.
  • Gradually pour in the milk and continue to stir until slightly thickened, about 5 minutes.
  • Remove saucepan from heat and stir in cheese, pepper and onion relish, salt, and pepper.

To assemble the subs

  • Take a sub and dig out the bread. Place some of the fajita mix inside until it's comfortably full.
  • Top the sub with the queso relish and garnish with desired toppings. Repeat until all subs have been assembled.
