I chopped the onion and mixed it with 1 teaspoon olive oil, nuked it for 1 minute uncovered, then added sliced zucchini and tomato and 1 teaspoon curry powder (you may like to use less if you like it less hot!). Then covered and microwaved the lot for a few minutes till soft, and put it through the blender. Added a tad of salt, and well, it wasn't too bad!
