In a large skillet, heat 2 tablespoons of olive oil over medium heat.
Add the minced garlic to the skillet and sauté for 1-2 minutes until fragrant, being careful not to burn it.
Add the shrimp to the skillet, seasoning with salt, pepper, and red pepper flakes if using.
Cook the shrimp for about 3-4 minutes, turning occasionally, until they turn pink and opaque. Remove the shrimp from the skillet and set aside.
In the same skillet, add the remaining tablespoon of olive oil and the orzo, stirring for 1 minute to lightly toast the pasta.
Pour in the vegetable broth and bring to a boil. Reduce heat to low, cover, and let it simmer for about 10-12 minutes or until the orzo is tender and has absorbed most of the liquid.
Once the orzo is cooked, stir in the cherry tomatoes, lemon zest, and lemon juice. Return the shrimp to the skillet and toss everything together gently.
Remove from heat and sprinkle with fresh parsley before serving. Adjust seasonings to taste if necessary.
Notes
Adjust the amount of red pepper flakes for desired heat.
