Step 1

Heat one tablespoon of the oil in a 10-inch or 12-inch cast iron skillet set over medium-high heat until shimmering. Working in batches, add the mushrooms to the pan in a single layer. Brown for 1 to 2 minutes per side; transfer to a bowl and repeat with remaining mushrooms.

Step 2

Add the remaining tablespoon of oil to the pan; add the onions and sauté until lightly browned, about 3 minutes. Add the garlic and sun-dried tomatoes and cook until fragrant and softened, another 2 minutes.

Step 3

Add the diced tomatoes to the pan, along with the beans, artichoke hearts, salt, pepper, oregano, thyme, and sugar. Cover the pan and turn the heat down to medium. Let cook for about 10 minutes, until hot. Return the mushrooms to the pan and cook for another minute or two to warm them up.

Step 4

Garnish with chopped parsley and serve with plenty of crusty bread.
