How many calories are in chopped beef?

I need more information to answer this question accurately. "Chopped beef" can refer to many different things, and the calorie count will vary depending on:

* The cut of beef: Different cuts of beef have different fat content. For example, ground sirloin is leaner than ground chuck.

* How it's prepared: Is it cooked with added fat (like oil), or is it lean ground beef? Are there other ingredients added like spices or vegetables?

* The portion size: One ounce of chopped beef will have significantly fewer calories than a whole pound.

To get an accurate calorie count, please provide me with more details about the chopped beef you're interested in.

For example, you can tell me:

* The type of beef: (e.g., ground chuck, sirloin, flank steak)

* The cooking method: (e.g., grilled, pan-fried, baked)

* Any additional ingredients: (e.g., oil, onions, spices)

* The serving size: (e.g., 3 oz, 1 cup)

With this information, I can give you a more precise calorie estimate.
