I just ADORE all the soups (apart from tomato yikeeeees) and eat them all hot. It makes me feel like I have a proper meal. Sometimes I even put them in a soup bowl and eat with a spoon.
I also drink all my sweet shakes warm (especially now in the winter), in summer I would put shake and ice in a blender and get a nice milkshake-like drink.
I have also tried putting coffee in vanilla shake but didn't think much of it. Also, try mixing allowed teas with sachets, that might work for you.
My favourite soup is chilly, followed by veg.
One warning-don't go for lactose free variety as they taste really really chalky.
