Waht I eat in a day (3) snack

I cannot jump from lunch to dinner without eating something. I need a snack as a fourth meal.
The kind of snack will depend on what I ate for lunch, if it was filling or not enough, and how many calories I already had.

Snack:
One very simple snack is one portion of  humus and raw vegetables, that I enjoy a lot; 2/3 rice crackers with peanut or almond butter, a small hand of dried fruits and a hand of nuts, a non-dairy non-flavored yogurt (coconut or soy milk). An apple with peanut/almond butter. But I also do very often at work: one banana,

or a cereal and nuts bar (220 cal), with a clementine. (Not both, one or the other !)
All my snacks go with a tea (my favorites: ginger/lemon, moringa, hibiscus, rose). It helps me getting to dinner time. Calories: roughly 200 cal for a snack (it can be 300 or even 100, depending again what I previously ate in the day)
