No, it is not greedy to have a small cooked breakfast and then curry for dinner (tea). Greediness is generally associated with excessive or selfish consumption beyond what is reasonable or necessary. Enjoying different meals throughout the day is a normal part of a balanced diet and a typical eating routine for many people.
Having a small cooked breakfast and then enjoying curry for dinner is perfectly acceptable as long as it fits within your daily caloric and nutritional needs. What's important is that you are eating a variety of foods to ensure you are getting a well-rounded diet that provides all the necessary nutrients your body needs.
As with any meal planning, it's a good idea to consider the nutritional content of your choices. Make sure your curry contains a balance of proteins, vegetables, and healthy fats. And, if your breakfast is smaller, try to include some nutritional elements like fruits, whole grains, or proteins to start your day off well.
Remember, everyone's dietary needs and preferences vary, so as long as you are mindful of your overall diet and eating in a way that makes you feel satisfied and nourished, there's no reason to worry about enjoying a variety of foods throughout the day.
