When I was on full liquids, I found that a few spoonfuls of McCormick prepared packaged gravy mix was a wonderful treat to break the monotony. I couldn't eat a bite of Healthy Request creamed Soup (not because my tastes changed, but because it's inedible)-- but liquefying and straining Progresso Light soup also worked really well for me.
I'm just about 6 weeks out now, so while I'm on soft foods-- full liquids is still a very vivid memory.
I still drink a Protein shake a day, especially after the gym. Today I tried SF Carnation Breakfast Essentials with a scoop of nectar Unflavored and 8oz. of unflavored coconut milk. Inexpensive, and not bad-- but only 16g of protein. Next time I'll try it with 2 scoops of Nectar Unflavored to bring it up to 26g of protein. Despite having extensively experimented with protein powders, I still haven't found the magic combination-- but mixing it up has helped.
Good luck!
