New relatives from India to visit. Any advice would be much appreciated.

Don't go through a lot of trouble, because they "don't eat much".
Yeah, okay.

Either one or both of them has legitimate dietary concerns, or they've already decided whatever you make isn't going to be good enough; and/or that you're too stupid and unrefined to know not to offend their basic sensibilities.

I wouldn't bend over ass-backwards to please such snide, snooty little pricks, if that were the case.

They'd eat whatever the hell I made, or not eat.

Damn right. I've had people turn their noses up at the food I made after I spent hours slaving in the kitchen making it. I never bothered cooking for them again. I have a high opinion of my cooking, so anyone who treats my hard work like crap can go order McDonald's instead.

I just hate that because I normally enjoy cooking for other people.
