Wash the potatoes
thoroughly and boil them in sufficient water in a deep non-stick pan till half done. Strain and keep aside.
Take refined flour, salt
and black pepper powder in a mixing bowl, add the potatoes and mix well till they are all well coated.
Heat sufficient oil in a
deep pan and deep-fry the potatoes till crisp and golden. Drain on absorbent paper and set aside to cool. When cooled press each potato to flatten them slightly.
Take mayonnaise,
tomato ketchup, onion, parsley and lemon juice in another bowl and mix well.
Add the potatoes and
toss till everything is well combined.
Spread lettuce leaves
on a serving platter, place the potato salad on top of it and serve immediately.
