@lucaannibale I just have a basic kitchen scale. I had 4-5 dishes that were simple to make and had decent macros, and ate mostly those over and over for a couple of weeks. Breakfast and lunch were basic, and then i'd vary dinner to fill out my macros. For example, I'd place a bowl on the scale, and then drop 250g of yogurt, 2 scoops of protein, 150g of granola, a banana, 60-70g peanut butter. Easy to weigh, not a huge volume of food, but close to 1400kcal and 100g of protein.
You can top it off with different berries, or add Chia etc. Lunch can be a Chipotle burrito or something similar, etc. Things you can easily vary a bit, but that are easy to make and give you good calories and protein. My default is to assemble vs spend time cooking while in this weighing process to just make things easier for myself. So a can of beans, two cans of tuna, some tomatoes, maybe a microwaved sweet potato, hot sauce, this makes it easy to weigh so it's not a chore.
