Green smoothies need help?

Okay so I can't stand vegetables and I'm really think about making a fruit and veg smoothie. But a wanna know can u taste the vegs? I'm nervous about trying it! An what should I start with? I love bananas apples grapes and sometimes oranges? But what vegetable to I pair any if those with I know that the fruit to veg is 60:40 but I'm lost I heard iceberg lettuce had no real favor which is good for me on taste but it's not full of what most people look for in a veg? Help?? And what does a green smoothie taste like? I really wanna know if the vegetables are strong in them. Thanks!!
