For the Soup

Step‑by‑Step Instructions for High-Protein Vegetable Soup
Step 1: Sauté the Aromatics
In a large pot, heat 2 tablespoons of olive oil over medium heat. Once shimmering, add 1 chopped onion and 3 minced garlic cloves. Sauté for about 3-4 minutes, stirring occasionally, until the onion becomes translucent and fragrant, creating a flavorful base for your High-Protein Vegetable Soup.
Step 2: Add the Vegetables
Stir in 2 diced carrots, 2 chopped celery stalks, and 1 diced red bell pepper. Continue to sauté these veggies for an additional 5 minutes, allowing them to soften and sweeten. The mix should be bright and colorful, inviting the deliciousness to come.
Step 3: Introduce the Broth and Lentils
Pour in 6 cups of vegetable broth and add 1 cup of rinsed dried lentils. Bring the soup to a vigorous boil, then immediately reduce the heat to a gentle simmer. Let it bubble away for about 15 minutes, allowing the lentils to cook through and soften beautifully.
Step 4: Incorporate Beans and Herbs
Once the lentils are tender, add 1 can each of chickpeas and black beans, along with 1 teaspoon of dried thyme, 1 teaspoon of dried basil, and salt and pepper to taste. Stir well and let your High-Protein Vegetable Soup simmer for another 10 minutes to blend all the flavors harmoniously.
Step 5: Add the Greens and Peas
Now it’s time to bring in the greens! Add 2 cups of chopped kale, 1 cup of green beans, and 1 cup of frozen peas to the pot. Cook for an additional 5-7 minutes, until the kale wilts down and the green beans are bright and crisp-tender, infusing the soup with vibrant color and nutrients.
Step 6: Final Touches
Remove the pot from heat and stir in the juice of 1 fresh lemon and a handful of chopped parsley. These final touches will brighten up the soup and enhance the flavor profile. Give it a taste and adjust the seasoning with extra salt, pepper, or lemon juice as desired.
Step 7: Serve and Enjoy
Ladle your warm High-Protein Vegetable Soup into bowls, garnishing with extra parsley if you like. This nutrient-packed, hearty soup can be enjoyed on its own or served with crusty artisan bread for a comforting meal that nourishes both body and soul.
