I’m Punjabi and we eat both meat and veg dishes. There are dishes that are common to a variety of desi cultural groups (daal, palak, etc).
How about a mutton pulao and chicken tikka? That way you’ll have one chicken dish and one red meat dish as opposed to two dishes with chicken. For salan, you can make a vegetarian one. We usually make either palak or cholay.
Mutton palao
Chicken tikka
Palak or cholay (I think cholay would fit in very nicely with brown rice and chicken tikka. Murgh and cholay combo is popular.)
salad

I think it sounds good. If you’re having a small gathering, I think this menu is simple, but hearty and balanced. You have two different types of meat. You’ll have both rice and roti/naan. And you also have a veg dish. And your have your sides. You’re done
