Recipes/Foods for people with high blood pressure

Anybody have food recipes for people who has high BP?

My husband (who I need to make a Dr appointment for since he's stubborn)

Possibly has high BP as his most recent reading at a dentist appointment was 155/108

I'm wondering what he should and shouldn't be eating

I have SOME experience as my pregnancies were high risk due to high BP

But I don't know much most likely will ask doctor tons of questions but haven't set appointment up since he works a lot and got to schedule around that
