Frozen spinach from garden
Frozen broccoli from garden
Frozen zucchini from garden
Frozen corn from garden
and as I'm working in the kitchen cooking up the meat and making freezer meals, I just put the scraps into a pot with water to cover. After it boils, I strain the peels and scraps out, and then use the liquid in my soup.
In crockpot all day on low. Yum. And super inexpensive.
