Strawberry Lemonade Slushy

1 20 oz blender bottle
juice and zest of one lemon
8 roughly diced strawberries
10-12 ice cubes
2-4 tsp sweetener (to your taste. I usually go 3 tsp of Apriva or a mix of Apriva and sugar.)
water

Fill bottle with the lemon juice, zest, strawberries, ice, and sweetener.

Add about 3-4 inches of water.

Blend.

Shake it up a couple times and blend again.

You may need to add more water to make it more of a drink.

This is a thick, fruity icee..
