In a mixing bowl, combine mayo, ketchup, garlic powder, paprika, and hot sauce to make the yum yum sauce.
In a skillet, melt 1 tablespoon of butter over medium heat. Add shrimp and cook until pink, about 3-4 minutes. Add 2 tablespoons of soy sauce and stir.
Add zucchini, onion, and remaining butter. Sauté until vegetables are tender.
Push the shrimp and vegetables to one side, crack the egg into the skillet, and scramble it. Mix everything together.
Add peas and carrots, cooked rice, and remaining soy sauce. Stir well and heat through.
Serve in bowls topped with yum yum sauce.
Notes
You can adjust the amount of hot sauce based on your spice preference.
