I do one with a softened onion, a couple of garlic cloves,gently fry add stock (we use veggie cubed) and a teaspoon of miso paste. To this I added brocoli florets, pepper, julliene carrots, peas, sweetcorn, baby broad beans (edamame would be better but I didn't have any in)I suppose you could add whatever veg is in the fridge that would work. I also popped some dried seaweed in. And the noodles when everything was still crisp but cooked iyswim.
Went down a storm and tasted like the wagamamas yasai ramen
