There are a couple of threads with photos of lunches and dinners on here, with the occasional recipe.

Primal recipes: I've enjoyed websites such as OMGPaleo, Against All Grain, Cupcakes to Crossfit, and Chocolate covered Katie (vegan, but typically gluten free; decent for desserts) but for the most part, I take recipes that I would have made pre-paleo, or recipes that aren't marketed as paleo/primal , but adjust it to be a bit more paleo friendly.

Here's one that I made yesterday that I like, but my husband didn't. He wasn't fond of the spaghetti squash, but likes the sauce.

Almond Apple Biscotti

I used this recipe but baked it as a loaf, think next time it needs 45 minutes at 350 not just 30. Then when loaf is cool, cut into slices and bake again, a minimum of 10 minutes per side at 350 to dry them like biscotti. Mine was a bit crumbly because of cooking it only 30 minutes to start. And I think next time I would make 2 logs like a real biscotti recipe instead of using a loaf tin.
