If it's your first time making a smoothie with spinach, start small and work your way up. I typically add two handfuls to mine.
Fresh banana and frozen peach will work as will using both fresh or both frozen; the great thing about smoothies is how ridiculously versatile and customizable they are. Simply adjust the ice depending on your fruit's chill factor. If you're using all frozen fruit you'll need less ice and if everyting you toss into the blender is fresh? Get your ice on! You can always add additional ingredients after your initial blend so don't fret if you're winging it!
Blend and enjoy!
