Anyone use their gear/recipes to help with faith based eating practices?

Lent starts this week. I don't fast because of health reasons but I will be trying to abstain (from meats) more. My son does not yet have to fast but figure I would use this season to emulate what he will be doing in coming years. I am thinking of promoting using bentos for the season (it should be easier to meet fasting rules if you pack your own meals). Any suggestions??
