Super easy and super good.
This is crock pot sorta stuff (i suspect you could even "cook" it in the microwave)
Saute some onion
1 can of whole kernel corn
1 can of black beans
2 cans of GREEN enchilada sauce
2 or 3 handfuls shredded chicken
chili powder and other seasonings as you see fit (jalapenos, pepper, salt, etc)
We often top our bowls with shredded cheese and sour cream. Toss in some tortilla chips and/or some warm tortillas and yum, yum.
