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...
Quinoa salad is easy and doesn't take a lot of effort. Cook the quinoa like rice - twice as much water as quinoa and then bring to a boil, turn it down to a simmer for about 15 minutes covered. Then toss that with whatever veggies you have on hand - I love it with tomatoes, cucumber, feta and olives for a "greek" twist.

Then you dress with either bottled dressing or vinegar/lemon juice and olive oil. Versatile and its even better the second day.
