Give me a recipe using eggs, salt, potatoes, onions, and tomatoes.
Here's a recipe for a classic Spanish dish called Tortilla de Patatas or Spanish Potato Omelette that uses eggs, salt, potatoes, onions, and tomatoes:

Ingredients:

4-5 medium-sized potatoes, peeled and sliced into thin rounds
1 onion, chopped
4-5 eggs
1-2 tomatoes, sliced
Salt
Olive oil
Instructions:

1.In a large non-stick pan, heat 3-4 tablespoons of olive oil over medium heat.

2.Add the potatoes and onions to the pan and sprinkle with a pinch of salt. Cook, stirring occasionally, until the potatoes are tender and the onions are translucent.

3.In a separate bowl, beat the eggs and add a pinch of salt.

4.Drain any excess oil from the potatoes and onions, and then add the egg mixture to the pan, making sure it covers the potatoes and onions evenly.

5.Cook the omelette over low heat for 8-10 minutes, or until the edges start to set.

6.Place the tomato slices on top of the omelette, cover with a lid or foil, and continue cooking for another 5-7 minutes, or until the eggs are set and the top is lightly browned.

7.Once cooked, use a spatula to carefully slide the omelette onto a plate. Serve warm or at room temperature, sliced into wedges.

This dish can be served as a main course or as a side dish, and it's perfect for breakfast, lunch or dinner. Enjoy!
