I sometimes precook the raviolis and keep them in a single layer on a parchment - lined baking sheet until I am ready to use them - this helps prevent the raviolis from melding into one another after cooking.
you just plug it in, put in an half an English muffin or sometimes homemade biscuits, meat (precooked bacon, sausage pattie, or ham, cheese, then crack a farm fresh egg and top with other half of English muffin.
