Question: Anyone know of any good resources for cooking recipes/methods/tools for people with a medical condition that causes chronic fatigue? I'm relying too much on convenience foods and 'tv dinners', because frequently the effort of cooking a decent meal is beyond my energy limits at the end of the day.

Answer: 
Having a wife with CF, I can appreciate your difficulty. You have the combination of not being able to put the effort into cooking, and the decreased ability to handle food with poor nutritional content (like most TV dinners). 

One thing I do is to always cook about about double what we need for a meal and then either refrigerate or freeze the leftovers in meal-sized portions. Otherwise, we try and have healthy foods easily available for snacking - pre-washed spinach, good hearty bread, nuts, etc...
Get a good blender. Blending food is a way to make quick drinks and soups. There are tons of quick recipes online. Vegetable drinks require just a quick rinse and minimal chop. Same with fruit smoothies. Yogurt smoothies are easy. A good blender will even heat a soup just from blending it for 5-10 minutes on high. You can even add (cooked) meats, eggs, or other proteins to the mix. 

The obvious advantage is no pans, no cooking, minimal prep and cleanup. On the gustatory side, I'm not trying to recommend a bland, geriatric, babyfood diet. Blended foods can be well-seasoned and taste great. Add oil, onions, spices, salt, pepper to savory dishes. Honey, cinnamon, vanilla to smoothies. Lemon juice, lime juice, even condiments can add zip.

A big blended drink or soup with a hunk of toasted whole grain bread and butter is an easy and delicious combo. You could make bulk amounts and easily save leftovers.

Plus, it's fun to experiment, and doesn't require too much hassle or expertise.

It's well outside the scope of this site, but blending foods makes them easier to digest. Complete speculation, but I bet that easier nutrient absorption would be good for CFS. 

There are some commercial products: the Vitamix, Montel William's blender, the Juiceman juicer which target some of these goals. I find a regular blender works great, though it obviously doesn't remove fiber (like a juicer, not always a good thing anyway), and you have to cut you food a little smaller if it's a lower powered machine.
