Food Pack Alternate Recipes & more trade contracts

Food packs are great for trade for Oil & Uranium -maybe more in future.
It would be nice however if there were more combinations of foods that can be used to produce them.
Currently Meat or Eggs (Protein) + Snacks (Treat) + Bread (Carbs)
It would be nice if you could create food packs with any 3 out of the 4 categories to provide a good disposal route for all excess food. Obviously there is a balancing issue here that would need to be addressed so that there is no "Meta" way of producing them.
Keep up the good work!
