Add all the ingredients into a freezer zip top bag and stash in the freezer until you need a quick and delicious meal.
Place a nonstick pot over medium heat. Add in a drizzle of oil and the contents of the freezer bag. Cover and cook until the veggies have separated and are no longer part of one large frozen block, about 10-15 minutes. Uncover and cook until most of the water has cooked off, about 10 minutes.
Drizzle in enough oil to lightly coat the bottom of the crockpot. Add the contents of the freezer bag into the pot. Cook on low for 4-6 hours or until the veggies are tender.
