Put the potatoes, cut into 4cm chunks, into a large pan with the garlic. Cover with water and bring to the boil, then reduce the heat and simmer for 15-20 minutes until the potatoes are very tender. Drain and return to the pot. Add the milk, yogurt and cheese, and season to taste. Mash until mostly smooth.

Cook on the hob over a medium-high heat for 10-12 minutes until slightly thickened. Spread the mashed potatoes over the top of the lentil mixture. Transfer to the grill and cook for 2-3 minutes until the mash is beginning to brown. Let stand for 5 minutes, then serve.
