Paneer / Tofu / Chicken Tikka Sandwich

Mix all the marinade ingredients in a bowl, adding enough yogurt so it coats the protein easily.

Add the paneer / tofu / chicken, cover, and let it sit at least 30 min (or marinate overnight).

Heat olive oil in a pan and add the marinated protein along with the extra marinade.

Stir-fry a couple of minutes, then cook covered 15-20 min, mixing now and then — you'll see some water release.

Uncover and cook till the water mostly evaporates and it's neither too dry nor too watery, with some golden-brown colour. For chicken, make sure the meat is cooked through (it takes longer than the veg proteins).

Butter both slices of bread.

Spread coriander green chutney on one slice and ketchup on the other.

Arrange lettuce and onions on one slice and squeeze some lemon over the onions.

Add the tikka on top of the onions, close the sandwich and enjoy!
