Step 1: Combine flour, salt, and yeast in a large mixing bowl and whisk together well.
Step 2: Add warm milk and warm water to bowl with dry ingredients. Stir wet ingredients into dry ingredients creating a shaggy-mass.
Step 3: Add olive oil and knead the dough together using your hands, ensuring all stray bits come together.
Step 4: Cover the bowl with plastic wrap, lay a kitchen towel over, and let rest for 1 hour.
Step 5: Dust a clean work surface with flour and place dough down. Using your hands, work it out into a flat circle.
Step 6: Cut dough into 6 equal pieces. Working with 1 piece at a time, roll each piece into a ball. You should have 6 equal sized dough balls. Cover dough balls with a towel while rolling out each one.
Step 7: Using a floured rolling pin, roll out one ball into a circle that is about 1/4 inch thick. Repeat with remaining 5 dough balls.
Step 8: Heat a large pan over medium-high heat and spread a small amount of olive oil. Place pita down and cook until bubbles form, about 30 seconds. Flip over and cook for 1-2 minutes or until bubbles on bottom side are golden-brown. Flip over again and cook 1-2 minutes more until both sides are toasted evenly.
Step 9: Keep cooked pita bread covered with a kitchen towel. Repeat with remaining pita dough.
