Lawnboi,
I really don't have any favorite recipes to pass on, like you I don't go in for a lot of prep or cooking steps. I do like some variety in flavors though so I will try different types of the boxed carb meals (rice, pasta, humas, etc.) which gives me a lot of variety. I just this week tried the Idahoan mashed potato mixes and they are super easy to make (mix boiling water with the powder and it's ready in a few seconds...literally a few seconds) and it tastes great; they come in about a half dozen "flavors" to give you lots of variety and calories.
I like to add vegetables to my meals as I am trying to maintain a balanced diet that is more than just meat and carbs, which most backpacking food seems to be. Unfortunately, finding dehydrated/freeze dried vegetables is difficult or you have to get them in large containers over the internet. So, to get my veggies in I am going to try using soup starter kits/mixes.
One other thing to consider, if you want to do more than just add water and eat, is to carry either a small frying pan (which I have for my JetBoil) or a wider/shallower pot and use that with your stove to fry/simmer/sear or in other ways prepare your protein or starches for your meal. FBC meals are good but you can also incorporate grilled chicken or fish with it instead of just boiled/reheated chicken or tuna.
Also, even though the recipes you looked at were more work than you normally want to do, you can always use some of those techniques to give yourself some variety. For example, making pudding or other desserts.
Come to think of it I do have a favorite breakfast using FBC...I like oatmeal or other hot grains (grits, cream of wheat, etc.) and to change it up some I will add fruit and...wait for it...pre-cooked bacon or bacon bits to it. The raisins or dried fruit adds sweatness to it and the bacon adds a savory twist. Together it works well, at least for me, and you get a better mix of nutrients. To do it I mix one or two oatmeal packets, some milk powder, one of those little boxes of raisins, and some bacon bits in a quart freezer bag...add the hot water and set it aside in a cozy to cook/rehydrate.
