Ummmmmmmmmmm... ya know I saw that and was trying to actually think of some stuff...
I never really freeze anything... I will generally fridge things because I'll eat them within 24 hours (usually within like 2 hours to be honest) of when I cook them.
But... things that would likely freeze and re-heat well...
Well like you said, baked Ziti...
What about like Lasagna? Lasagna would likely reheat pretty well without too much trouble.
Caseroles would be pretty good... mainly I'd say anything that is like a one-dish item. If you have like a mixed plate in 5he freezer when you reheat it, you'll be re-cooking it and different things may not re-cook as well as others.
Certainly wouldn't do vegatables, especially since you could go buy some frozen peas or corn or something and just heat them up whenever.
Don't know if you like meats, if you do (can you even eat like steak when pregnant??? :shrug
but with any meats... first time you cook them, I'd undercook them a bit since when you reheat them they will re-cook themselves...
Mashed potatoes may not be bad... but when you reheat them maybe ya know... re-add some ingredients, throw a little butter, maybe a touch of milk in on them...
:shrug:
I'll keep trying to think for ya, that's what I got off the top of my head though...
