1. Preparing the Potatoes and Onions:
   • Peel the potatoes and grate them using a grater with large holes to ensure texture in the cake.
   • Rinse the grated potatoes in cold water to remove excess starch, then drain them well.
   • Slice the onions into half rings for a sweet, caramelized flavor when cooked.
2. Cooking the Vegetables:
   • Heat a bit of vegetable oil in a frying pan.
   • Sauté the sliced onions (and bell pepper strips, if using) in the pan until they’re soft and golden.
   • Season with salt to taste. Remove from heat once cooked.
3. Preparing the Egg and Potato Mixture:
   • Grate the cheese.
   • Beat the eggs in a bowl with a pinch of salt.
   • Combine the beaten eggs with the grated potatoes thoroughly.
   • Mix in the corn starch to bind the ingredients together.
4. Assembling and Cooking the Potato Cake:
   • In a new pan with a bit of heated vegetable oil, spread half of the potato mixture to form the base.
   • Add a layer of grated cheese and the cooked vegetables, followed by another layer of cheese for that melty middle.
   • Cover with the remaining potato mixture.
   • Cook covered on medium heat for about 10 minutes, then flip and continue cooking for another 15 minutes on low heat. Remove the lid towards the end to crisp up the exterior.
