It's not as sweet as ketchup, it's a bit runnier with a stronger tomato (not sugar sweet) flavour. It's balanced 50/50 savoury sweet:
Tomato Sauce (51%) [Tomatoes (29%), Water, Sugar, Salt, Maize Thickener (1422), Food Acids (260, 330), Flavours], Navy Beans (49%). May Contain: Soy

When on toast, you can load up the toast for the ratio you like. It's honestly fine.
