Not too similar, but I used to dip frozen grapes in nut butters. Later I started mixing Greek yogurt into the butter to lower the calories. Sometimes I’d add honey, cinnamon, or dried fruit! It’d be a good dip for granola.
You’re asking for things to dip into dips, right? Most people are assuming you’re asking for a low calorie dip, so you might want to clarify if I’m reading it correctly.
Anyway, the answer is veggies. Carrots, cucumbers and celery are the classics. Apples and pears are good too.
