Make the Avocado Cilantro Cream:
Blend the avocado, Greek yogurt or sour cream, garlic, lime juice, cilantro, salt, and pepper until completely smooth. Add 1ā2 tablespoons of water if needed to achieve a silky drizzleable consistency. The mixture should be creamy and bright with a subtle herbal aroma. Chill in the refrigerator while preparing the shrimp so the flavours develop and the sauce thickens slightly.
Assemble the Bowls:
Add warm rice to each bowl and drizzle with a small amount of butter or lemon juice if desired. Top the rice with the lemon garlic shrimp, arranging them so the juices seep slightly into the rice. Spoon or drizzle the avocado cilantro cream generously over the shrimp. Garnish with chopped cilantro. For extra crunch and freshness, add diced cucumber, cherry tomatoes, or thin slices of red onion.
