🌿 Celery

Celery adds crunch and freshness while being very low in calories. It provides hydration, fiber, and important antioxidants that support digestion.

🧄 Garlic

Garlic boosts flavor and immunity. It has antimicrobial properties and supports heart health by helping manage cholesterol levels.

🍅 Tomato Sauce or Diced Tomatoes

Tomatoes bring acidity, richness, and umami to the soup. They’re high in lycopene, an antioxidant linked to heart health and reduced inflammation.

🫘 Black Beans (or any beans)

Beans are a powerhouse ingredient — high in protein, fiber, iron, and complex carbs. They help keep you full longer, stabilize blood sugar, and support weight loss.

🥕 Frozen Peas and Carrots

Frozen veggies are just as nutritious as fresh and super convenient. Peas add plant protein and fiber, while carrots provide beta-carotene for eye and skin health.

🥬 Cabbage

Cabbage is one of the most affordable vegetables and adds bulk, crunch, and fiber to soups. It’s great for digestion and very low in calorie density.

🥔 Potatoes

Potatoes are incredibly filling and nutrient-dense. They provide potassium, vitamin C, and resistant starch (especially when cooled), which supports gut health and satiety — perfect for weight loss.

How to Make Clean Out the Fridge Soup

There’s no wrong way to make this — think of it as a formula rather than a recipe:

1. Sauté onions, celery, and garlic in water or veggie broth until softened.
2. Add vegetable stock, tomatoes, beans, potatoes, cabbage, and any other veggies you need to use.
3. Simmer until everything is tender and flavorful.
4. Season with herbs, pepper, garlic powder, onion powder, bay leaf, or whatever spices you love.

Taste and adjust — every batch will be slightly different, and that’s the beauty of it!
