Protein snacks

I need some ideas for high protein snacks that have at least 10g protein (20g or less carbs and under 200 calories). I have food allergies that keep me from eating peanuts, tree nuts and anything soy. Looking for easy things to take to work for a snack and after workouts.

I've grown to love the Aldi brand of plain Greek non fat yogurt (23g protein!) But need some more variety!

Thanks for any help you can give!
