After the preliminaries, what I've cooked so far.

In February 2009, my first meal was made consisting of a Ramen-like noodles and seasoning packet.  Between the end of February and the middle of March, I had purchased and used several noodle Ramen-like clusters that had been purchased with $1 for 10 clusters w/o the seasoning packets.  The noodles themselves take a little longer to rehydrate than the typical Ramen noodle and have a slightly more stale taste to them.  The benefit has been three-fold:  one, I don't spend a lot of money; 2. the stale taste motivates me to make them taste better; 3. I can have a relaxed attitude about failed experiments.  

With the noodles, I have made plain chicken seasoned noodles (twice),  spaghetti w/ real cheese, mushroom pasta using a left of bit of processed mushroom sauce that goes with another style of noodle, and maybe two more experiments (I don't remembering what I made). 

I've made instant oatmeal from a packet and a homemade oatmeal using instant oatmeal (with seasons and dehydrated blueberries). 

I have purchased and have plans to make items using gravy and an instant mashed potato mix.  Of course, there are many sorts of basic add water and boil recipes, but i will be avoiding using most of them because they take a long time to boil the food item and/or because I think I have a way to make a homemade version that will be healthy (I am not a health nut guru).
