I recently switched to dehydrated/freeze dried raw but I am currently mixing with about 30% Orijen 6 fish kibble with Pet Kelp Priobiotic supplement and sometimes a spoonful of plain yogurt. I also give fresh fruits and veg as treats and give them chicken necks or rabbit spines in place of 1 meal a couple times a week. I tried adding in fresh tripe and I feel terrible but my stomach just couldn't handle it. 
The idea of homemade raw is really intimidating to me and like you I barely spend time cooking for myself so it isn't really sustainable on a daily basis. I also have next to zero freezer space. I found the dehydrated raw a good alternative because although it's not the optimal nutrition compared to fresh or frozen raw, it is better than kibble.
There is a place called Posh Nosh in my area that makes prepared frozen raw food. Maybe there is something similar in your area. They have stuff like mango chicken casserole, ground meat with bone, different organ meats, pureed fruits and vegetables, all types of raw bones, etc. etc. They are already portioned out so you can just take one out of the freezer as needed. I tried feeding this to my girls but it REALLY upset Gracie's stomach so that's how I ended up with the dehydrated raw. It's working really well for them so far but then again I never had any issues feeding them just Orijen.
I've used two types so far: NRG and Honest Kitchen. From what I have read on review sites (to be taken with a grain of salt I know) it seems HK might have better ingredients. Based on the dry texture and smell though it seems like the NRG has more substance to it - HK is more like sawdust consistency until you add water. I buy small bags every couple weeks and rotate the type of protein.
The only thing I don't like about the dehydrated raw is I like to give Lady's food in the Kong Wobbler every morning, and this can only be done with kibble which is why I've kept Orijen in the mix.
