To me, cold meals taste much better compared to hot meals.

Cold foods and drinks actually limit the flavors you can taste in food. The temperature of foods change the sensitivity of taste receptors (primarily for sweet, salty, and umami flavors), the amount of/intensity of aromatics released by the food, and the textures of fats, gels, and syrups.

It is all down to preference, of course. But if you prefer the flavor experience of chilled foods that are normally served hot, then you likely prefer foods that are less/more subtly sweet, salty, and savory, and more sour and bitter. You likely do not care as much to the aromatic smells of food that accompany and enhance/alter the flavors of food. And you probably prefer the firmer, thicker textures of foods that would usually be softer and thinner with heat.

The downside with foods being cold, health-wise, if you do like things to be sweeter, for example, is that you need far more sugar to get the same sensation of sweetness from a cold food (like ice cream) than a warm food (like pie). Same with saltiness. A cold soup needs more salt than a hot one, usually.

Alternatively, warm fatty foods spread fat-soluble flavors across the tongue while cold fatty foods usually block taste receptors more while providing little flavor itself. So if you're cooking for the purpose of eating the food cold, maybe you'll use less fats and save yourself some calories/cholesterol and also get more flavor in that form factor at the same time.
