Copsec,
I have a real hard time believing you can buy the things you mentioned for $135 a months, that comes out to 1.50 per meal. The chicken alone would cost more than that. Are you in the USA?
Wife and I spend about $90-100 per week. That does include ice cream, chips, soda, some frozen dinners. If we really tightened up we could maybe go down to $60 per week, But NoAp would be one sad person.
