Shell and blanch the peas. Blanch the peas by placing them in boiling water for 1 1/2 min then place into ice water to cool, then drain. In a small skillet, brown the pre diced pancetta until almost crispy, drain on paper towel. In a bowl combine the mint, shallot, lemon zest, olive oil, salt and pepper. Add peas, pancetta and sun dried tomatoes and fold together. Toss in crumbled feta.
