Preheat grill over medium-high heat.

Cut peaches in half and remove the stone. Brush with oil and sprinkle with salt. Place on the hot grill. (If you don't have a grill use a hot saute pan.) Cook until soft but not falling apart, approximately 3 minutes on both sides. Set aside to rest.

In a small bowl mix the mascarpone, cream cheese and powdered sugar together until it reaches a smooth consistency. Use a little hot water to loosen, if mixture remains stiff.

To finish place 2 halves of the grilled peaches onto a plate. Top with cheese mixture and drizzle with raspberry sauce. Garnish with fresh chopped mint.
