You could put your daily menu up, with a recipe if needed. Inspire your readers to try something "new" with you.

Or make a list of healthy snacks. I recently did this (if you want a copy e-mail me).

I have this book of random questions and if I was a little less lazy at the moment, I'd dig it up for you. Alas. I did find this article of ideas: http://onlinejournalismblog.com/2009/02/04/starting-a-blog-12-ideas-for-blog-posts/

I like the guest blog idea. Stargirl is going to be guestblogging for me soon.

Ooooor you could blog about this really awesome necklace that you unfortunately had to pay for.

Me, too.
