Cook up some instant mashed potatoes (any flavor, plain is fine).  Put them in a casserole dish and then slice cooked hot dogs or sausages lengthwise and poke them around the perimeter of the casserole dish.  
I know that sounds dumb, but it is really good.
Macaroni and cheese is quick and easy, as is spaghetti.  Nachos is always good; steak only takes about 15 minutes under the broiler.  Add those instant potatoes, canned green beans, and you've got a decent enough meal.
Any of us could go on for a long time with easy, but I've got to get to dinner...at a restaurant. 

Grilled Cheese on Sour Dough bread, side dish of frozen mixed vegetables, V8 juice, cut up a couple of oranges and sprinkle them with a little sugar add a banana and maybe a few walnuts before serving, glass of sweet soy milk. (Yum)  Time ... about 8 minutes.   

We never have a "regular" dinner anymore. We keep it easy and healthy this way. 

Steak, onion and salad toasted sandwich,with some chips.
