Would it be better to eat shalosh seudos before davening Mincha, or to wash after Mincha and after shkia (which, according to the Chazon Ish and others, is assur)?
Answer:
Better to eat before Mincha.
If you have a regular minyan for davening Mincha there is no problem in eating before davening, and this is common practice in many communities.
Best wishes.
