Warm the olive oil in a heavy bottomed skillet over medium-high heat. Add the garlic and cook for 30-45 seconds, until it starts to soften. Add the thawed artichoke hearts, parsley, salt, pepper, and red pepper flakes and cook until the artichoke hearts are starting to brown at the edges, about 3 minutes. Add the vegetable broth and Marsala wine to the skillet and simmer for 3 minutes. Transfer the artichoke mixture to a 2-quart rectangular baking dish.
Melt the butter in the same skillet you cooked the artichokes in. In a small bowl, mix the melted butter with the crushed brown rice cereal and chopped almonds. Stir in the Parmesan and top the artichokes with the crumbs. Bake until the top is golden, approximately 8-10 minutes.
Sprinkle additional chopped parsley over the top of the dish and serve immediately.
