2. Preheat 1 very large or 2 large skillets over medium flame.
3. Lightly coat onions with oil spray and put in hot pan, stir and cook for 3 minutes, add peppers and continue to stir for 3 more minutes.
4. Drain meat and cook with pepper mixture (or in the second skillet if you do not have room in one pan) for 3 minutes stirring constantly.
5. Spread 2 teaspoons of mustard on each flatout flatbread.
6. Distribute meat mixture evenly between the four flatbreads and roll.
