Lightly coat a large skillet with cooking spray. Preheat over medium heat. Add the potatoes, green onions, peppers, cumin, and garlic. Cook and stir about 3 minutes or until the vegetables are tender.
In a small bowl stir together egg product, milk, and cilantro; add to skillet. Cook, without stirring, until mixture begins to set on the bottom and around the edge. Using a spatula, lift and fold the partially cooked mixture so uncooked portion flows underneath. Continue cooking and folding until egg product is cooked through, but is still glossy and moist. Remove from heat.
