Instead of trying to collect more recipes, think of dinner as an opportunity to right your nutritional wrongs - a sort of edible confession. Whatever nutrients you may have missed during the day...make them the highlights of your last meal.
An hour or so before you cook, order or take-out , run through a quick checklist:
1. Veggies?
2. Fruit?
3. Protein?
4. Healthy fats?
5. ETC?
If you haven't had enough or (gasp!), there's no check mark at all - that's whats for dinner! Simple.
