• Preheat oven to 350 degrees.

Prepare Enchilada Sauce:

• Heat olive oil over medium heat in a medium skillet.
  
• Add garlic and saute until fragrant, 30 seconds to 1 minute. Whisk in flour and chili powder and cook, stirring constantly, for 2 minutes.
  
• Slowly whisk in broth until smooth, and then stir in tomato sauce, cumin, and oregano. Reduce heat and simmer for 15 minutes.
  
• Remove sauce from heat, then season to taste with salt.

Prepare Black Beans:

• While the enchilada sauce is simmering, heat oil over medium heat in a large skillet.
  
• Add garlic, cumin, and oregano to oil. Cook, stirring constantly, for about 30 seconds or until fragrant.
  
• Add black beans to skillet, then cook until black beans are thickened, stirring frequently.
  
• Remove beans from heat, then smash about ½ of them with the back of the spoon. They should have a creamy texture; add a little water if they're too thick. Season with salt to taste.

Assemble Enchiladas:

• Spray a 9 x 13-inch baking dish with nonstick spray, then cover bottom with a thin layer of enchilada sauce.
  
• Cut the cream cheese into 12 equal pieces, then arrange it, along with the black beans and tortillas, so they are all within easy reach for assembly.
• Heat a small non-stick skillet over medium-high heat.
  
• When hot, add a tortilla to the dry skillet. After about 30 seconds or so, carefully test the tortilla with your finger. If it feels warm, grab it and quickly flip it over. Cook for a few seconds on the other side - the tortilla should be heated through and flexible - and then remove from skillet. (I use my fingers for this, but feel free to using tongs if the tortillas get too hot.)
• Spread a piece of cream cheese down the middle of the tortilla and top with 1/12 of the black beans.
  
• Roll tortilla up tightly and place in baking pan. Repeat with remaining tortillas.
• When all the tortillas are filled, cover them with the remaining enchilada sauce, then sprinkle with cheese.
• Bake enchiladas for 30 minutes or until hot.
  
• Serve enchiladas topped with cilantro and avocado. Enjoy!
