Though the concept sounds tasty it certainly does not sound simple nor too healthy in this day and age. The peach filling does not need so much butter or sugar nor the cream. Soaking the assembled sandwiches is tricky. Perhaps cooking one side of the saturated bread slices then placing the filling on top of the cooked side, then topping with another cooked side and then continuing to cook like a grilled cheese would be easier.
I would give this ONE star, only because I haven't tried it. Until calorie counts are readily available, I shall read the recipes, drool sometimes, but not try them. But not try them.
This recipe contradicts all that RealSimple stands for. It is not simple! It uses a skillet (possibly two), a cutting board (needed to specify the one with grooves or instead to use a jellyroll pan), a bowl, a baking sheet, and possibly another bowl (or having to wash the first one) for beating the cream. Too much cleanup for a sugary breakfast. I am not willing to go through that in my kitchen in the morning.
