Isolation meal recommendations

What consists of a healthy meal, would completely depend on the composition of the rest of the diet, goals, whether its a training day or non training day etc.

Thus I find giving specific recommendations in isolation difficult, without seeing the rest of the diet.

Having said that: protein should usually always be the main proponent of a meal, as well as possibly fibre (depending on whether fibre targets have been met or not), from there a composition of proteins & fats would make up the rest of the meal, in amounts suitable to meet your goals. The composition of all three macro nutrients (protein, carbohydrates & fat) would depend on what has been eating previously & what you plan to eat the rest of the day, if at all.

A meat or fish
With rice & vegetables within a meal maybe considered healthy to most, however this completely ignores what has been consumed the rest of the day. Thus this meal could potentially lead you into a caloric surplus, thus leading to fat gain (minus any of that surplus being used for muscle gain).

The moral of the story is to look at the day as a whole rather than obsess over isolation meals, while ignoring energy balance for the day. Whether that meal example I have above would help you achieve your goals would completely depend on the amounts within that meal & what is about to or has been consumed throughout the rest of the day.
