How long are their stuffed peppers good for past the sell by date?

I freeze em, tasty after thawing.

Not a go bad date, (used for freshness) as long as they still solid with no bruising or soft spots should be OK ( no longer than 10 days give or take), look it up on Google to assist

Sell by date, is mainly just for quality freshness but I'd probably a week or two would be the longest past sell-by-date.
