Using a coffee grinder, grind oats until fine.
In a small bowl, add ground oats, flour, and flax seeds; knead well by adding a little water at a time to form a soft dough. If the dough is too sticky, sprinkle with flour
Divide the dough into four parts and form four round flat patties.
On a rolling board, spray the cooking oil for 1 second; start rolling the patty dough with a rolling pin in a circular motion until it is 5 to 6 inches in diameter.
Pre-heat a non-stick wok or a griddle on medium-low heat; place the chappati on the wok or the griddle for 2 to 3 minutes. Flip and cook on the other side for an additional 2 to 3 minutes.
Remove from heat and store in an airtight container to keep moist.
