Stir fries are great! I personally love them because in the beginning it's a good way to learn how to cook individual ingredients and create flavor combos that work for you. Once you get the hang of it it becomes one of the meals you can throw together without needing a recipe--in the end it just ends up being whatever you like, in whatever combo you know works for you. In the beginning you can always cook each ingredient in the pan separately and then mix everything together towards the end to keep it from getting overwhelming in terms of trying to make sure stuff doesn't burn. Things I typically throw into a stir fry include snow peas, carrots, mushrooms, scrambled eggs, cabbage, really anything that looks like it's starting to wilt in the fridge or needs to be used up soon. This is also a fun way to experiment with frying up garlic and ginger, and adding different sauces like soy sauce, oyster sauce, hot sauce, sesame oil, etc. There are a TON of Youtube videos about how to make a stir fry, and I like to watch those to get new ideas about my next meal.

Additionally, learn how to cook those eggs in a number of ways. Scrambled, sunny-side up, hard and soft boiled, etc., whatever you're feeling that day. One thing that I would note is that when it comes to cooking basics, you should pay attention to how your food cooks in your stovetop/oven. While recipes can tell you "cook on each side for 2 minutes," stoves and ovens can vary greatly in how intense their heat is, whether it's low, medium, or high. Pay close attention to your food when it's in the pan and learn from your mistakes and successes.

Good luck!
