Patch, have you tried to cut pumpkin, aubergine (use other veg if you like) into thick chips, toss in oil, you can use coconut oil if you want, then ovenbake till golden, season with salt, paprika, whatever you fancy.
Do comforting veggie mash, you can even sneak in a small potato or sweet potato, it wont cause that much damage.
Re cauliflower rice, I season it with salt, pepper, butter and a couple of sprinkles of Maggi liquid seasoning - if we are having curry I soften half a finely chopped onion, a bay leaf, couple of cardamom pods and a bit of cassia bark or cinnamon stick, do this really slowly so it doesnt burn, and until the onion is golden, slightly brown at the edges, then stir in your cauliflower rice and its ready, it really does make a very acceptable pilau rice, even non diabetic friends and family like it, esp since its a good way of increasing vegetable intake.
All the best
