Nutrition Information

It’s a great source of plant-based protein from the lentils.:
Full of fiber, which helps keep you full and satisfied.:
Packed with vitamins from the spinach and tomatoes.:
Naturally low in fat, especially if you go easy on the optional vegan cheese.:

First, we use one pot. This saves you time on cleaning and energy on your stove. It’s a small change that makes a big difference at the end of a long day.

We also rely on pantry staples like canned tomatoes, broth, and dried pasta. These items are inexpensive and have a long shelf life. You can buy them in bulk when they’re on sale.

Instead of pricey vegan meat substitutes, we use brown lentils. They give the soup a wonderful, hearty texture. A bag of dried lentils is incredibly cheap and goes a long way.

My Tips for Smart Shopping on a Budget

Being a savvy shopper is a skill anyone can learn. Here are a few of my favorite tricks.

Buy your lentils, beans, and pasta dried instead of canned or pre-cooked. The price per serving is much lower. A little prep work saves a lot of cash.

Choose store-brand canned goods and vegetable broth. The quality is almost always the same as name brands. But the cost is significantly less.

If you can, buy your onions and garlic in big bags. They are the flavor foundation for so many meals. Buying in bulk almost always gives you a better price per item.

The Budget-Friendly Ingredient List

Here is everything you’ll need. Check your pantry first—you might already have some of these items!

  • 1 tablespoon olive oil

How to Use Up Every Last Bit (No Waste!)

I hate throwing food away. Here’s how to make sure every part of your grocery trip gets used.

If you have extra spinach, it’s perfect for smoothies or a quick side salad. Just toss it with a little lemon juice and oil. Wilt it into scrambled tofu for a quick breakfast, too.

Leftover vegetable broth can be frozen in an ice cube tray. These broth cubes are perfect for adding flavor to rice or sauces later. It’s a simple trick that prevents waste.

If your onion is too big, chop the extra and freeze it. You can toss frozen onion directly into your next soup or stew. No need to thaw it first.

Common Questions About This Recipe

It’s normal to have questions when trying a new recipe. Here are answers to the ones I get most often.

Can I use a different type of pasta?

Absolutely! Any short pasta will work well. Try mafalda, rotini, or even elbow macaroni. Just adjust the cooking time based on the package directions.

How long do the leftovers last?

The soup keeps beautifully in the fridge for up to 4 days. The noodles will soak up some broth, so you may want to add a splash of water or broth when reheating.

Is it freezer-friendly?

Yes, but I recommend freezing it without the pasta. The noodles can become mushy when thawed. Cook fresh pasta and add it to the thawed and reheated soup base.

I hope this recipe becomes a new favorite in your home. It’s a dish I turn to again and again when I need something comforting, healthy, and affordable.
