I usually do it night before like boil the egg and and mash it to make for sandwich and in the morning I just put it in bread.And for fresh fruit like straw berries I usually put in the ziploc in morning.
Here is a chicken cheese kebab recipe:
Boneless chicken
boil potatoes
Cheese ( I usually use mozeralla )
cabbage (a little)
salt
black pepper
chaat masala
First you boil the chicken with one garlic clove ,salt and pepper and let the water dry itself.No need to throw away the water.When the water is dried mash the chicken,mix cheese,boil potatoes, cabbage, salt, black pepper and chaat masala in it.And freeze it when u have to fry it use bread crumbs and eggs.First dip it in egg and then bread crumb.After that pan fry it until it turns golden crisp.
