Would it be OK to substitue a juice for a meal? I do well with breakfast, lunch and the snacks but dinner's a bit harder to prepare since I get home so late. I will, at some point, begin to prepare some dinners ahead of time (casseroles and meals like that - quick quinoa salads, vegys) and that will help of course. But when I'm really pressed, hungry and need something quick - I start reaching for the bread and almond butter. Could I substitue a juice for dinner?
