1. Heat olive oil in a large pan over medium-low heat. Add garlic and cook until fragrant, about 1 minute.
2. Pour in chicken broth and bring to a boil over medium-high heat. Stir in orzo, lemon zest and juice. Season with salt and pepper to taste then reduce heat to medium-low.
3. Simmer until orzo is tender, stirring once halfway through, about 10 minutes in total.
4. Meanwhile, heat a separate pan to high heat. Add the lemon slices and cook just until lemon begins to char, about 3 minutes per side. Remove and set aside. Add cherry tomatoes to the same pan and cook until soft and blistered.
5. Once pasta is cooked through, remove from heat and stir in Garlic & Herb Whipped Dip, charred tomatoes, and arugula. Garnish with charred lemon slices and additional zest, if desired.
