Is there a word for when you have an idea that is a really good idea, but you feel dumb for not thinking of it sooner, because it seems so obvious once you have it?

A few years ago there was this variety of pasta sauce we used to eat a lot that had chnuks of Italian sausage in it. Then the brand discontinued that variety. For a long time I would look forlornly to see if it had come back on sale. Other brands make a similar type of sauce but we didn't like them as much.

Today I had my idea: I could buy the same brand of sauce, and a package of Italian sausage, brown the sausage and put it into the sauce myself. Victory! But I feel dumb for not thinking of it sooner.
