@mrstumbler you could put loads of vegetables in the slow cooker, top up with stock. Add lentils and black beans for example. Some garlic and chilli if you fancy. And cook on low for 8 or so hours. Then blitz if you want it smooth.
So many variations, you could add different vegetables at a time. Different herbs and spices.
My go to for a high protein meal is Dahl. Just fry the herbs and spices, garlic in some coconut oil and add to slow cooker, add some stock, some coconut milk and a packet of rinsed red lentils. Leave on all day, mixing a few times throughout.
You can look at recipes for inspiration, but you don't have to follow exactly.
I currently cooking a black bean and chickpea version, with tomato to alter the taste.
Takes the thinking work out of it, and you know what you're putting into your body.
Once you cut carbs and sugar out, your taste buds adjust and your body just wants to be fed for nutrition.
So if you're on a limited calorie diet, it's super important to make every calorie count.
