12 snap beans is 20.5 calories. according to the tracker 3/4 of the Westpac frozen green beans is 22.5 calories. The short answer is eat the 3/4 of a cup.
At 30 calories a cup though, I think you don't really need to worry about the serving size. If you have a cup, or even 2, green beans aren't going to ruin your diet. Fresh or frozen only matters in how it measures. They are the same food. Frozen may not pack as densely, so you may want to eat a cup to make sure you get enough, while fresh will pack down more, and 3/4 cup may be the same. The difference in the 1/4 cup is 7.5 calories, so don't spend too much time obsessing about it.
