1. Stir-fry the spaghetti separately from other ingredients, so that the spaghetti can be fully fried until it is fragrant. Lazy people who don't like to fry in separate pots can fry onion and beef first, then put green and red peppers, and finally put spaghetti, so they can all be fried at once;

2. Please refer to the product packaging for the cooking time of spaghetti. Different brands have different cooking times. Generally speaking, the shorter the time, the more expensive the spaghetti is (in France, spaghetti cooked for 5 minutes is more expensive than spaghetti cooked for 1 1 minute);

3. The amount of black pepper is adjusted according to personal taste, and people who are afraid of spicy food should put less. It is recommended to buy black pepper granules and grind them into powder when you finally put them in.
