its okay to eat 3meals...but just don't eat more than your calorie needs. eat more meals times a day...will increase your metobolism.
But i'll suggest to eat less after the taraweeh... cause there are some research that to eat 3 hours before you sleep or your food will not properly digested.
Have fun with variety of foods...and don't stick only some types of food. Experiment with them! :D
