The recipe came from here, it's a version of Bieler's Broth:
1 pound of string beans
2 pounds zucchini
a hand full of curly parsley
enough water to cover your veggies
lemon pepper (or just pepper) and salt to taste
Into rapidly boiling water add above and boil for 10-15 min until fork goes thru outside of zucchini, puree using the water you cooked it in and make it the consistency you desire.
