Indian food is not healthy haha! Everything has tons of oil in it. Oil and onions is the base of almost every dish. They use alot of curry powder which is full of salt. Tandoor is actually the oven they use to cook the "tandoori" items in. You can have tandoor chicken, kabobs (beef), goat, lamb, fish, shrimp etc. Its coated with tikka masala which is a mixture of spices combined into one. They also add yougart and lemon to this maranade. Chicken tikka masala is a yougart and whipped cream dish with plenty of spices and oil. its suppose to be eatin with roti -tortilla made of wheat- or naan -flat bread-. tandoori naan are the best because they are oven baked and fresh. samosas are the best..they are appetizers that are little triangles filled with either ground beef or roasted potatoes with seasonsing and clenatro and pees, you dip them into "chuntney" which is yougart, green peppers, cilantro,mint and salt. they have diffrent varaiations of chutney, but this one is the most famous.
They also have bryani--which is white basmati rice cooked with either veggies or beef or chicken. its really good. Also, they have other dishes like nihari, which is a beef stew cooked which you eat with naan or roti. anyways, there is A TON more of food. i spent the summer in pakistan, Iran and palestine and saudia arabia..so im very familiar with the food in those areas...lemme know if you have any questions!
edited to add: gulab jamman is the best desert! its flour balls cooked in syrup and then left in syrup until they get a bit soft...its the most fattening thing in this world haha! there is a ton more of things I could tell you, but id be here forever
