Steamy meatballs covered by tomato sauce and served with processed cheese and bread. My favourite junk food would have to be a meatball marinara served with Italian bread from Subway.

1. The marinara sauce adds sugar and salt to the dish
2. There are a high amount of fat in the meatballs. A foot long contains 36 grams and a 6inch contains 18.

These chips ingredients are:

Potatoes, Vegetable Oil, Seasoning (Lactose, Sea Salt, Wheat Maltodextrin), Sodium Acetate, Acetic Acid, Malt Vinegar Solids (Contains Barley), Malic Acid, Citric Acid). Contains Milk, Wheat And Barley Ingredients.

The additives would be the

Sodium Acetate and Acetic Acid which are used for tartness

Total calories per 28 chips(50 grams) is 260 and the fat for 28 chips is 15 grams which means for a whole bag is it almost 5 times that amount.

Lastly I enjoy eating lots and lots of chocolate, that is where I get most of my sweetness from when I have a sweet tooth. Now although I am a huge fan of 70% dark chocolate, my favourite chocolate would have to be:
