Can you break Lent on Sundays?

Is it okay to break your Lenten fast on Sundays?

I’ve heard from a few friends and people at church that they do, since Sundays are considered “feast days” and not part of the 40 fasting days. Personally I’m not planning to break mine on Sundays, but I’m curious what others have been taught or practice.

Is this a common thing? Does it depend on the church?
