How many calories in iceberg cucumber tomato red onion and spring salad with a touch of lemon juice?

I can't give you an exact calorie count for your salad without more information. Here's why:

* Portion Size: How much of each ingredient are you using? A single serving could be a small side salad or a large bowl.

* Dressing Amount: "A touch of lemon juice" is very vague. How much lemon juice are you using?

* Other Ingredients: Are there any other ingredients in your salad, like dressing, croutons, cheese, or nuts? These will all add calories.

To get a good estimate, I recommend:

1. Use an online calorie calculator: There are many free online calorie calculators. Simply enter the ingredients and the amount you are using.

2. Check nutrition labels: If you're using pre-packaged salad ingredients, check their nutrition labels for calorie information.

3. Estimate based on general guidelines: Here are approximate calories per 100 grams of some common salad ingredients:

* Iceberg lettuce: 14 calories

* Cucumber: 15 calories

* Tomato: 18 calories

* Red onion: 40 calories

* Spring mix: 25 calories

* Lemon juice: 21 calories (per tablespoon)

Remember, these are estimates. The most accurate way to determine the calorie content of your salad is to use a food diary or calorie-tracking app.
