I'm not from that culture particularly, but everyone needs to eat, and going to a nice restaurant can be a pain (e.g. transport) and be expensive as well. Having people into your home for a meal is a very good alignment of a lot of things at once; that's why cultures have been built on it.
Order some food, it doesn't even need to be from fancy restaurants. Low-end to cheap catering and delivery services (so not Uber Eats or such). You can prepare some appetizers at home if you really want some home made food.
Depending on where you order the food... people might not even realize you didn't cook it.
Slightly off topic, as we don't do this for guests, but one thing I do for cheaper takeout (which we have extremely rarely anyway) is order curry but cook rice at home. Although these days ready meals from some supermarkets (I'm in the UK) are pretty great, and you can get a half-decent curry for £3 or so, and again just cook your own rice.
