Next time I feed an omnivore, like my neighbour, I'll quiz them as to how 'omnivore / carnivore friendly' they think the recipe is and will report back! I've a fair few straight-vegetarian recipes that can satisfy the most hardened carnivore but, I must admit, most of the low-carb veggie ones that I've done so far have probably been a bit 'light' for meat-and-two-veg folk.
I think one needs reasonable quantities of legumes in a recipe for an omnivore to be satisfied - the Thai bean cakes or the spiced lemony lentils might do it, and quorn mince, of course (but that feels like cheating).
The VBF is veggie but rather a carb addict and she has actually been surprised at being satiated by all the low-carb dishes that I've fed her, and that's without a third helping!
I'll try to keep the carb addicted carnivore in mind when I'm working on recipes in future FatDog
