Making stuffed potato cakes is a simple yet rewarding process. Follow these steps to create your delicious cakes:

1. Cook the Potatoes: Boil the cubed potatoes in salted water until they are fork-tender, which usually takes about 15-20 minutes.
2. Prepare the Filling: While the potatoes are cooking, combine the cooked lentils, corn, green onions, cumin, smoked paprika, salt, and pepper in a mixing bowl. Stir until well combined.
3. Mash the Potatoes: Once the potatoes are done, drain and mash them in a large bowl until smooth. Allow them to cool slightly.
4. Combine Mixtures: Fold the filling mixture into the mashed potatoes gently. Ensure everything is evenly mixed.
5. Form the Cakes: Take about a handful of potato mixture and shape it into a cake or patty, about 2-3 inches in diameter. Repeat the process with the remaining mixture.
6. Coat with Breadcrumbs: Roll each patty in gluten-free breadcrumbs until fully coated to add extra crunch.
7. Heat the Oil: In a large skillet, heat olive oil over medium heat. Ensure there is enough oil to cover the bottom of the pan.
8. Fry the Cakes: Place the patties into the hot oil, cooking for about 4-5 minutes on each side, or until golden brown and crispy.
9. Drain Excess Oil: Once cooked, transfer the potato cakes to a plate lined with paper towels to absorb any excess oil.
10. Cool Slightly: Allow the cakes to cool for about 5-10 minutes before serving.

Following these steps, you will create crispy on the outside, soft on the inside, stuffed potato cakes that everyone will love.
