TIPS: You can adjust this and use any vegetables (ie. zucchini, sweet potato) - but don't overdo the amount of vegs and try not to overcook until it's too mushy. You can also add greens that you need to use up - cabbage, spinach. You can also use frozen spinach that you've microwaved or frozen peas put straight in . You can also add 1 can butter beans (drained) into soup about 5 mins before serving. You can use this basic formula for any veg soup. Another way to thicken soup is to take about 1 cup of the veg + liquid and blend with 1 can of drained white/brown beans ie: navy and pinto. Then return to soup pot. Adjust to your taste. This soup freezes well - I put 1 cup amounts in freezer bags for quick reheating.
