Confession: Sometimes after eating bread I substitute
"brich rachamana malka d'alma ma'arey d'hai pita"
("blessed is the merciful one, ruler of the world, creator of this bread.")
in place of the entire birkat ha'mazon.
It doesn't feel quite right, but.... it's got to be better than saying nothing.
