Melt butter in a large saucepan over medium heat.
Add garlic (minced), sage, lemon pepper seasoning, salt and mustard powder. Cook for 1 to 2 minutes, or until garlic is fragrant.
Stir in flour until combined, then slowly drizzle vegetable broth.
Bring to a gentle simmer until sauce thickens.
Stir in chickpeas (drained), cover, and let simmer for about 5 minutes.
Remove pan from the heat then stir in heavy cream and chopped Italian parsley.
Garnish with sliced lemons and freshly ground black pepper! (Sauce will continue to thicken as it cools.)
