Bring a pot of boiling water together. Cut an x at bottom of peaches. Immerse in water for a minute or two. Cool. Peel peaches. Dice. Set aside.
On medium heat, add oil, butter, onion, until translucent.
Season meat with salt and pepper.
Add meat, break up with fork, and when no pink color is showing.
Add milk. Turn down heat to simmer, stirring frequently until milk has evaporated.
Add wine, stirring thoroughly. Once wine has completely evaporated, add peaches and tomatoes, and simmer on very very low stirring every now and again. If sauce dries out, add ½ cup water a time.
Add herbs (to be removed later).
Cook for a minimum of 3 hours. I think 4-6 hours is better.
Taste and season with salt, pepper
