In a large mixing bowl, combine the flour, salt, lukewarm water, and vegetable oil. Mix until smooth. Knead the dough for about 10 minutes until it's elastic. Cover the dough with a clean towel and let it rest for 30 minutes.

While the dough is resting, combine the sliced apples, granulated sugar, raisins, cinnamon, and lemon juice in a large bowl. Set aside.

Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.

On a floured surface, roll out the dough as thinly as possible. Transfer it to a clean kitchen towel and carefully stretch it to achieve a paper-thin consistency.

Spread the bread crumbs evenly over the stretched dough, leaving a small border around the edges. Spoon the apple filling over the bread crumbs.

Using the kitchen towel, gently roll the dough into a log starting from one long side. Transfer the strudel to the prepared baking sheet.

Brush the strudel with melted butter and bake for 35-40 minutes until golden brown and crunchy.

Let it cool slightly before slicing to allow the filling to set for easier serving.
