Step 1

In a medium bowl, whisk flour, baking powder, and salt.  Slowly stir in warm water with a fork.  Mix just until the dough comes together. Use only as much water as you need for the dough to come together. Cover with wrap and let rest for 1 to 2 hours. Flour your hands and the working surface. Pull off a piece a little smaller than a golf ball. Roll into a ball, then pat it out to 1/8 to 1/4 inch thick.

Step 2

In a heavy pan, heat 1-2 inches of oil to 375 degrees. Fry until the bread is golden brown and puffs up, about 2-3 minutes.  Flip halfway through to brown the other side. Remove to paper towels to drain.

Step 3

In a large skillet over medium heat, brown ground beef.  Drain any excess grease.  Add taco seasoning and water; simmer for 5-10 minutes.  Spoon on top of fry bread and sprinkle with cheddar cheese, tomatoes, black olives, and green onions.  Top with sour cream and serve immediately.
