The best "meal" for weightloss is a no-meal.
Eat a steak with some Kerrygold, some bacon, a little bit of grassfed beef liver pate, a sweet potato, and some mixed greens with EVOO. Skip the sweet potato if you're worried about gaining fat.
Are you including any tubers (e.g. sweet potatoes) after workouts with a little fat and protein? Post work out, I want something easy with all three in a scramble with some bacon, like my recipe here.
A proper answer would depend on what you mean by 'work out' (exericse, intensity and duration) and how much fat you need to lose.. are you at 45% or 20%.
Almonds are an easy snack to take with you, with a good balance of protein, fat, and very few carbs.
They're also delicious. :)
How about Water? Meals shold be 3/day or less as needed by using your hunger (not desire) levels as needed. If you are eating healthy/balenced and taking say probiotics to ensure that the vital nutreitns you are ingesting are getting into your system then you are fine.
I use a protein shake for post workout. increases muscle synthesis which, in turn, increases metabolism. Also the heavy punch of protein keeps me full till dinner. But that's me. YMMV.
Meal for weightloss?
That is an oxymoron. The best "meal" for weightloss is a no-meal.
