The meat-based products with olive oil and feta prepared in line with the aforementioned method have exceptional solidness, as far as structure is concerned, and retain the physical-chemical characteristics of the olive oil and the organoleptic characteristics of the feta contained in the products. Using the aforementioned method, preparation of such products can be assured even without the incorporation of olive oil, with the addition of feta type cheese only.
