Method:
Zest and juice two of the lemons. Cut the third lemon into medium-thick slices. Combine lemon slices, lemon juice and lemon zest with oil, garlic, bell peppers, and salt and pepper in a large bowl. Set aside.
Strip artichokes of their leaves, cut out and discard their chokes and quarter the hearts. Add artichoke hearts to bowl with lemon mixture.
Prepare a hot grill.
Place the sausage links on the grill and grill until cooked through, 5 to 6 minutes on each side. Transfer to a serving platter and set aside to let rest.
Place the artichoke hearts, peppers and lemon slices on the grill, cooking on both sides until cooked through, about 4 minutes per side.
Transfer vegetables and lemon slices to platter with sausages, sprinkle with herbs, and serve.
