What is vegetable stock?
Vegetable stock is very similar to vegetable broth (and can def be swapped!) without much difference to most people. Vegetable stock tends to be more flavorful and contains less sodium. Yet both will work fine in any of these recipes. I do suggest picking an organic one and reading the label to make sure there are no sweeteners in it (yep, some brands add corn syrup to their broth... so crazy!)
