Pink! Glad to have you with us!
I realize that everyone has different situations in their lives...if you feel that you are super busy and just don't have any time to cook, that you are looking for a plan where you can mostly 'grab and go,' then you might want to look into a different plan, to be honest.
You can look at a ton of different plans and see which is for you by reading the 3FC book...it has awesome reviews! If you like the ideas of South Beach but need to have more processed food for the ease of prep time, you might consider doing Weight Watchers Core program.
If you really feel dedicated to SBD and can find the time to make food yourself, you'll do much better. The basic idea of SBD is to get away from as much processed food as possible...and to eat and feel healthier.
The Kraft foods are almost all pretty much chock full of things that aren't technically part of the plan...not sure why Dr. A did it other than to possibly make money or to try to get people who aren't doing anything different to eat a bit healthier. They are certainly healthier, as a whole, than many frozen dinners out there. I know the nutritionist here in town prescribes the SBD granola bars all the time because she says they are the healthiest option out of all the ones available.
Bottom Line: SBD can be pretty easy to do...but you will need to make most of your own meals. A frozen dinner here and there when you're in a pinch is one thing, but making them the majority of your meals is not going to help your health, though you may lose weight.
Hope you find a plan that you know is right for you...and that if SBD is the one, you'll post a thread where we can help you see how easy making most of the food yourself can be.
As to the pudding, while Barb is totally right about it being easier (and cheaper) to make your own pudding, I use the pudding cups all the time.
I find it much easier to stick with one portion....when I make my own I end up fudging on portion size.
That's just me though... I also like Kozy Shack's NSA pudding cups.
