A typical meal day if you seriously want to bulk up.
Breakfast - 2 Eggs
Lunch - Chicken & Salad Wholemeal Sandwich
Snack - 1 Piece of fruit
Dinner - 120g Salmon with 4 varieties of green veg mostly. Brown rice if needed 70g.
You could add another snack into this diet, it's up to you if your starting to feel hungry. This doesn't include relative supplements such as protein/creantine/bcaa and so on.
I would advise you eat other foods such as Tuna & Beef Jerky for that added protein. The example I showed you is probably around 100g protein on food alone, on less than 2,000 calories.
If your looking to increase size and muscle then I advise you eat around 7 meals a day but adding things like cheese/cashew nuts/more fruit per snack and so on.
