It helps to go through the habit of a meal, before eating it in a mindful way.
It is useful to explore how each sense feels while eating the main course: steak with salt,pepper and a touch of saffron.
Again, with dessert, mango and raw almonds.
Simpler the better.
Shorter the better.
Perhaps, journal out what you ate how it felt, what you experienced during the meal.
Sometimes, it helps journal before or after doing dishes.
