1. In a pot, bring water and salt to a boil. Slowly stir in the grits, reduce heat to low, and cook for 15-20 minutes, stirring occasionally until thickened.

2. Once grits are done, stir in butter and shredded cheddar cheese until melted and smooth. Remove from heat and cover to keep warm.

3. In a large skillet, heat olive oil over medium heat. Add shrimp, garlic powder, onion powder, and paprika. Cook shrimp for about 2-3 minutes on each side, until they turn pink.

4. Add chicken broth and lemon juice to the skillet, stirring to combine. Simmer for 2 minutes until sauce slightly thickens.

5. Serve shrimp over the warm cheesy grits. Garnish with chopped green onions.
