Are the healthy choice, steamed meals a good post workout meal (obviously with alot of other things, but as a base)?

Alot of the nutrition labels are as such:

serv. size is 1 meal
Total Fat: 3g
Sat. fat 0.5g
Trans. 0g
Poly 1g
Mono 1.5g
Cholest. 25mg
Sodium 290mg
Potassium 600mg
Tot. Carbs 53g
Dietary fiber 5g
Sugars 5g
Protein 18g

I want gains, not to maintain or lose.
