I make soups out whatever veg I have to hand (with varying results!). I just fry onions and garlic then chuck in the veg and stock, then blend when done. A nice one I've made recently is potato, kale/cabbage and chilli. I also make hummus in my blender sometimes (chickpeas, tahini, lemon juice, garlic, olive oil and a bit of water). How about smoothies? Banana, milk, strawberries/raspberries. You could also put the smoothie into lolly holders and freeze?
