Those zucchini look great! We use them in most things. A meal that's going to be thoroughly cooked, I tend to start with a base of carrot, zucchini and broccoli. No onion, and only rarely celery, because of partner's FODMAP issues.
Yesterday, I made drunken risotto, because it's delicious and because partner had an extraction over a week ago and still needs softer things to eat. I used carrot, zucchini , broccoli, and green beans. The original recipe was by Rachael Ray many moons ago, but we've altered it for our tastes and availability.
Here's the original on someone's blog:
Recipe Sharing: Drunken Risotto with Sausage and Spinach
We use half a cured chorizo sausage cut up rather than sausage meat, use port rather than red wine (less of, obviously, half a bottle of port, roughly one and a half cups), no nutmeg - instead paprika, smokey paprika, chili flakes, rosemary, sage, basil, and plenty of black pepper, and we add haloumi cheese at the end when the parmesan, butter and spinach go in. The original recipe is completely stovetop, too. I begin on the stovetop, add everything gradually, cooking the vegetables to tender, then putting in the herbs and spices, rice, and chorizo, then the liquids, then allow ten minutes with the lid on, taste and balance, then it goes in the oven for half an hour at 180C, then the butter, parmesan, haloumi and spinach go in, five more minutes and it's done.
