Germany has brands of bottled curry sauce that are great on white rice.
I've never seen them in the US... but mayonnaise and curry powder is close enough.
Ranch noodles, though, I've served to guests all the time. It is exactly what it sounds like. You squirt ranch dressing all over fresh elbow / corkscrew pasta, and ideally cool overnight. It's two-ingredient pasta salad. Ranch is buttermilk, garlic, dill, and a bunch of other spices. Great as a side. Add pepper.
