Storing homemade relish

[Finster]

Made a small batch of pepper relish with ingredients harvested from the garden. I have probably about a pint left over after using it to top tonight's hot dogs. Not enough to bother canning it.
ingredients are italian frying peppers, onion, fresh tomatoes, chopped garlic, salt & pepper.
how long will this keep in the fridge?
Anything I can add that would extend it's shelf life?

Just based on chopped garlic as one ingredient, and consulting www.StillTasty.com, 5-7 days in the fridge. To extend add vinegar.

I’d be interested in tastin it. May try it since no sugar.

Oil, or vinegar?

Edit: meaning, did you add either?

Otherwise, I’d add some lime juice and cilantro, and you got salsa, which you can eat with chips tomorrow and you won’t have to worry about how long it will last. (But that will keep about a week.)
