get a big pot and toss the oil and spices, including fresh thyme, in the bottom of it, and heat it to medium heat
once the spices are aromatic, toss the sausage in there and stir until just a little sizzly
add potatoes and carrots and/or squash and stir. throw some more thyme in there, why not.
toss the wine/lemon juice in and cook for just a bit longer, until the carrots or squash look bright
add diced tomatoes and broth/water, then cook until all veg are soft for a fork. salt to taste.
toss the spinach/kale in and cook a bit longer on a lower heat- this is definitely a soup that gets better the next day, but if you give it a good hour simmering on the stove from start to finish, the flavours should incorporate well. you might find you need more salt and seasoning if you're using squash instead of carrot, because it's a sweeter and more absorptive veggie. but i trust you. you're a good chef. believe in yourself!
serve with some fresh thyme, if you like. so aromatic, so amazing.
