Instead of cooking every night, could you maybe cook large portions on Sunday and eat that for the next few days? I usually cook two things on the weekend, and it gets me through most of the week (I rotate them for lunch and dinner). That way when I get home, I can work out, just reheat something, and then get on to doing the dishes, getting my stuff ready for the next day, and eventually wind down. Saturday is my big cleaning day, doing laundry, vacuuming, cleaning the bathroom, etc. During the week I just try to keep on top of the dishes and put my clothes away.

As others have said, I also go through phases when cycling is or isn't the forefront of my life. Right now, it isn't, but I've done more hiking/reading/strength training/gardening, so I don't feel like I'm missing anything.
