With a sharp knife, trim the tips of the sugar snap peas on both ends; remove the strings if they bother you and cut some in half lengthwise. Blanch the sugar snaps quickly, just about 30 seconds, and shock in ice water. Slice the radishes thinly into coin shapes or half-moons. Combine the peas, radishes, cheese and peppermint in a large bowl. Season with salt and pepper and toss with the lemon juice and olive oil. Serve with a sprinkle of Aleppo pepper and garnish of edible flowers.
