sandwich with a layer of butter, chicken/turkey slices and veggies

idk but i wouldnt consume it if it stayed in the fridge for more than 24h

look up tdee calculator. i’d advice eating at a slight surplus of calories, so if your tdee is 2300 calories for example, try to aim for 300 calories above that. as you are a beginner, you’ll make gains pretty quickly and eating at a slight surplus will help you to not gain much fat. after 5-6 months, you can go on a cut (eating at a deficit, i’d advice to eat 500 calories less than your tdee) for a bit until you’ve lost a bit of the fat you’ve gained along the way. then you eat at a slight surplus again

nuts. peanuts, almonds, hazelnuts… as snacks ofc. they’re pretty calorie dense and have healthy fats along with some protein. win/win
