A meatless soup turns low-cost dry lentils into a freezer staple.

Ingredients
- 1 1/2 cups (300 g) dry brown lentils, rinsed
- 2 cans (800 g total) no-salt-added diced tomatoes
- 3 large carrots (240 g total), diced
- 1 medium onion (150 g), diced
- 7 cups (1680 g) water
- 1 Tbsp (13.5 g) olive oil
- 1 tsp (2.1 g) ground cumin
- 1/2 tsp (3 g) table salt
Method
- Heat oil in a large pot. Soften onion and carrots for 5 minutes.
- Add lentils, tomatoes, water, cumin and salt. Bring to a boil, then simmer 25-30 minutes until lentils are tender.
- Season with additional salt and pepper to taste. Stir well and divide into six equal portions; add drinking water when reheating if it thickens.

How the nutrition estimates are made
Each recipe reports approximate calories, protein, carbohydrate and fat per equal serving of its stated base batch. P = protein; C = carbohydrate; F = fat.
One ingredient, one weighed amount
The source stores edible ingredient grams and a USDA FoodData Central SR Legacy record. Dry pasta, oats, rice and lentils use dry weights; raw and cooked meat use matching records. Water and measured seasonings are included.
The calculation
For each nutrient: multiply ingredient grams by the USDA value per 100 g, divide by 100, sum the batch and divide by servings. Round calories to the nearest 10 kcal and macronutrients to the nearest gram.
What can change the result
Brand, draining, natural variation and cooking losses affect the real meal. Canned black/white beans use cooked unsalted bean proxies. Red lentils use generic lentils. The method assumes all listed oil and edible food are consumed; it does not model nutrient retention or evaporation.
What the estimate does not claim
Sides, training-day additions, substitutions and allergy swaps are excluded. Sodium, vitamins and minerals are not reported. These are ingredient estimates, not laboratory results, an assessment of your whole diet or a daily intake target.
