I’m veggie and my OH isn’t, so to avoid cooking two meals, we tend to eat a lot of Quorn. Some of the more processed and prepared meals (eg pies) are carby (obviously) but the plain mince and chunks are fine. I became veggie in the early 80s and the only meat substitute was TVP. Now that’s what you would call bland! I suppose I am used to cooking with it so I don’t expect the flavour of the Quorn to be dominant. I would be equally happy with most of the things I make if we left the Quorn out, but it is a useful source of protein.
Favourite recipes include cottage pie with cauli mash, supreme made with lots of mushrooms and peppers, chilli, Bolognese with courgetti or edamame pasta, Thai curry. We like the wild garlic and parsley sausages, or the Cumberland ones, rather than the plain ones. Apart from that we also eat the peppered steaks, gammon steaks, meatballs, and broccoli & mozzarella escalopes (about 20g carb in one of those but if you don’t have carby accompaniments it might be manageable).
