This isn't the sort of dish I grew up eating, and indeed sausage stews or casseroles are fairly new to me. As a child, we had (meat) sausages fairly infrequently at barbecues. They were a novelty and eaten in a bun or with barbecue themed side salads. Perhaps as a result, vegan sausages now frequent either in buns or alongside potato and salad. However, Dannii's casserole caught my eye as a hearty cold weather dish and as something suited to my current preference for make ahead dinners. (The time immediately before our dinner is usually taken up with bathing and feeding Mini Bite.)
Dannii's casserole used turkey sausages so an obvious adaptation in my dish was to substitute veggie ones. I used the Linda McCartney brand, which is one of our most frequently purchased vegan sausage options. I also put one potato into the stew and paired it with pitta bread instead of a mashed potato side. I left out the beans as I eat so many of them in other formats, added some additional vegetables (carrot, pepper, spinach), and tweaked the seasonings.
