In a skillet, brown the ground beef. Drain.
Place ground beef back onto heat and stir in taco seasoning (prepared according to package)
Mix in refried beans, green chiles, and chipotle chiles. Stir to combine.
Lightly spray a casserole dish with non-stick cooking oil.
Spread ground beef mixture evenly in casserole dish and sprinkle Mexican cheese on top.
Use a pizza cutter to cut strips out of flour tortillas.
Lay tortilla strips criss-crossed over beef mixture and bake 20-30 minutes, or until cheese bubbles and tortilla strips are golden brown.
Add olive slices on top of tortilla strips to create "eyes."
Serve this Boo-rito Bake with sour cream, hot sauce, and extra tortillas, if desired.
