Welcome to the forum and the world of the Thermomix.
What to make first? What about a vege juice? Use ice cubes to help emulsify the veges to a smooth drinkable texture.
Bread would be the next option, there's a wonderful recipe
here. These are bread rolls, but JulieO made a loaf with the same recipe and it worked really well.
What about a delicious vegetarian pasta? Use a tomato passata and put in some grilled Mediterranean veges. Once you start you'll think of all sorts of things to make.
