A homogeneous mixture can be described as a mixture in which particles are divided uniformly. For example, sugar dissolved in water.
A heterogeneous mixture can be described as a mixture in which particles are not divided uniformly and are uneven. A heterogeneous mixture can be separated whereas a homogeneous mixture cannot be separated.
As the garlic bread contains uneven quantities of ingredients, it is a heterogeneous mixture. Also, the sides of the bread can be separated.
