Meal plan for tomorrow needs some reviewing if you'll help

This is my meal plan so far for tomorrow ( breakfast , lunch and snacks ) any suggestions /improvements ? Breakfast : a hard boiled egg and banana lunch : 4 oz chicken breast , 1/4 cup black beans , and 1/2 cup broccoli . Snacks : 2 clementines , cucumbers , bell peppers , and a Greek yogurt . I am also going to the gym tomorrow for an hour so will be drinking a smoothie with flax seed ? Still need to plan out my dinner . I have 1200 Cals a day so I'm trying to eat as healthy and low calorie as I can
