@Roberta,
Yeh, to make sure you get all the nutrients you need that aren't in pasta, etc.
I'll be interested in what the nutritionist has to say.
Wonder about something like packaged flan, or jello. (Never mind fancy mousse. Oh, wait, what about fancy mousse.. oh well, either too hard to get or too much trouble to make, and not the time for fancy flavor.)
I make baked eggs. Oiled pie plate or equivalent, then mix in a bowl 5 eggs scrambled, some bits of stuff - wonder about smidge of garlic powder.. little bit of grated/minced jack cheese? tiny bits of spinach? 5 tablespoons water, little olive oil, beaten a bit more and poured into pie plate - baked at, um, 360 for, um, 35-40 minutes. Comes out like quiche without the crust. Makes several meals for a single person. (Let cool, or refrigerate and let come to room temp.)
