Preheat the deep fryer to 375 degrees F.
Heat the oil in a wide-mouth pot. Saute the onions until translucent, then add the fish sauce, garlic, mixed vegetables, celery and some ground black pepper. Stir and cover, simmer for 2 to 3 minutes. Add the cabbage and stir until warmed through, but still crispy. Remove from the heat and drain in a colander. Cool the mixture.
In a small bowl, dissolve the flour in 1 tablespoon of water. Lay out a wrapper and place 2 tablespoons of the cooled vegetable mixture and one thawed French fry in the center. Fold two corners toward center of wrapper and roll tightly. Seal the end with a dab of the flour paste. Repeat for the remaining filling and wrappers.
Fry the rolls until golden brown, about 5 minutes. Drain the rolls on paper towels and serve hot with sweet chile sauce for dipping.
