Picking out your vegetables is the fun part. In the winter, we use a lot of squash because it is in season. In the summer I go for asparagus or brussel sprouts. (Thanks Roxie! I've never done roasted brussel sprouts until your recent post!) Use a variety of oils as well (olive oil, grapeseed oil, coconut oil).
I'm not going to post an exact recipe but just some ideas to try.
Brussel sprouts and garlic
Asparagus and rosemary, thyme, and sea salt
Curried squash (Rory HATES curry... much to my dismay)
sweet potatoes with cinnamon and coconut oil
