How many calories in a two egg omelette with spinach and mushroom?

It's impossible to give you an exact calorie count for your omelette without more information. Here's why:

* Egg size: Large, medium, or small eggs have different calorie counts.

* Cooking method: Frying in butter or oil adds calories compared to cooking with non-stick spray.

* Amount of spinach and mushrooms: A handful is different from a cup.

* Other ingredients: Cheese, seasonings, and other fillings all contribute to the calorie count.

Here's how to get a more accurate estimate:

1. Look up the calorie information for the ingredients you're using. Most grocery store websites and nutrition apps have this information.

2. Estimate the amounts you're using. Use measuring spoons or cups for more accuracy.

3. Add up the calories for all the ingredients.

Example (using approximate values):

* 2 large eggs: ~160 calories

* 1 cup spinach: ~40 calories

* 1/2 cup mushrooms: ~30 calories

* 1 teaspoon olive oil: ~40 calories

* Salt and pepper: ~0 calories

Total: Approximately 270 calories

Remember, this is just an estimate. For the most accurate information, use a food tracking app or consult with a registered dietitian.
