My understanding is they are not Core--at least not yet. Too many additional ingredients, and many are not whole grain.
What I sometimes do: make a Core soup or stew, freeze extra portions in small containers (like the Ziploc kind with the blue lids). Thaw one the night before you want to take it to work and reheat fully in the microwave.
I've done a lot of bean/grain soups--you can keep them interesting by varying the spices you use and the vegetables you add in.
The mirror of the heart must be polished daily.
