Best low calorie tasty snacks (particularly for that 3pm slump!)

[Eatsleepwork]

I'm loosely calorie counting and don't worry if I go over some days as I've pretty much reached my target weight. I have cut out most snacking but occasionally I just want a hot drink and a snack... I normally have a salt and vinegar rice cake or occasionally a highlights hit chocolate but does anyone have any nice treat type snacks that are low in calories?
I sometimes bake a fat- free fruit loaf that is über tasty but isn't low calorie. I eat lots of fruit but sometimes that just doesn't cut it!

Choppped apple mixed with a little walnut butter

Water

Chopped cucumber, red pepper and carrot. Keep it in the firdge.

It depends what you feel like ? 2 squares of Lindt dark choc with a touch of sea salt or a ryvita with some low fat ricotta and a tiny drizzle of honey or a ryvita with a thin slice of cheddar or an egg or half an avocado? Some very small biscuits / cakes aren't too bad if you stick to one? Or a bag of quavers?

Sweet rice cakes are quite nice. The Snack-a-jacks caramel are massive and nice and sweet and only 50 kcals.

30grams reduced fat cheddar cut into tiny squares (so it takes longer to eat) dipped in Horseradish sauce is my go to snack.

I like the sugar free jellies - they are 10cals or I have a pack of dried apricots or prunes
