unhealthy snacks are my weakness

I've noticed that my weakness is eating unhealthy snacks. I think i can have a some of this and some of that, but then i realize i've eaten so many stupid unhealthy snacks. Like today, I had bread with olive oil and some chocolate covered pretzels. Then it occurred that I need to plan healthier snacks ahead of time.

I need ideas of healthy snacks and small meals that I can have at home and on the go. I would love some suggestions!

Thanks!
