Preheat your oven to 425 degrees F. This step is essential for roasting the veggies perfectly.
Prepare your baking sheet by placing bite-size pieces of cauliflower and broccoli on it. Make sure they are spread out to allow even roasting.
Drizzle the veggies with 1 tablespoon of olive oil. This will enhance their flavor and help them caramelize.
Time to roast! Bake the vegetables for about 15 to 20 minutes or until they are soft when pierced with a fork.
While the veggies are roasting, prepare your brown rice according to the package instructions. It should be fluffy and ready by the time the shrimp is done.
As the rice cooks, heat the remaining olive oil in a large skillet over medium-high heat. This oil will be used for the shrimp.
Once the oil is hot, mince the garlic and set it aside. You want it fresh and aromatic for the next step.
Place the shrimp in the skillet in one layer, cooking them for about 1 minute. This allows them to sear nicely.
After a minute, add the minced garlic to the skillet. Stir it together and cook for another minute until the garlic is fragrant.
Add in the lemon juice, butter, and parsley. Allow the butter to melt while you continuously stir. Cook for 2 to 3 minutes, until the shrimp turn pink and the sauce thickens slightly.
Using a fork or slotted spoon, remove the shrimp from the skillet, setting them aside. You can leave the butter sauce in the pan.
With the remaining butter mixture, add 1 teaspoon of water to the skillet. Stir it to thicken the sauce and cook for 1 minute longer.
Serve the shrimp over the cooked brown rice, drizzling it with the butter sauce. Pair with the roasted veggies and fresh grapes on the side.
