Peel the potatoes and slice them thinly into small rounds or half-moons.
Finely chop the onion. Dice the tomatoes and cucumber, then set them aside for the salsa.
Heat 1 tablespoon of olive oil in a non-stick skillet over medium heat. Add the potatoes and about two-thirds of the onion. Cook gently for 12-15 minutes, stirring occasionally, until the potatoes are tender and lightly golden.
In a large bowl, whisk the eggs with the whole milk and salt until smooth.
Add the cooked potatoes and onion to the egg mixture and stir gently to combine.
Heat the remaining 1 tablespoon of olive oil in the skillet over medium-low heat. Pour in the potato and egg mixture, spreading it evenly.
Cook the tortilla for 8-10 minutes, until the edges are set and the bottom is golden. Carefully flip it using a plate, then slide it back into the pan and cook for another 5-7 minutes, until fully set.
Remove the tortilla from the pan and let it rest for 5 minutes before slicing it into sandwich-sized pieces.
Prepare the cucumber tomato salsa by mixing the diced tomatoes, cucumber, remaining onion, and fresh basil in a bowl.
Lightly toast the bread slices if desired.
Assemble the sandwiches by placing a piece of potato tortilla between two bread slices. Serve each sandwich with the cucumber tomato salsa on the side or spooned inside.
