I wouldn't recommend it. Peach salsa needs to be sweet (hence the point of employing peaches), regular salsa is tomato-based and therefore tart. The two will be fighting rather than complimenting each other.
Yes, but it might not be the type of peach you ate. Most fruit trees are grafted onto different root stock so the fruit's seed doesn't always make the type of tree you might expect.
peel mango. slice into 5-10mm widths, and cut into cubes. quarter a cucumber lengthways, remove seeds, slice and chop slightly smaller. really finely dice a shallot. deseed and finely chop some red...
