Make the Tomato and Garlic sauce:
Pour olive oil into a medium-sized saucepan set over medium heat.
Add garlic and cook until fragrant, about 30 seconds.
Stir in the tomato sauce.
Simmer until slightly thickened, about 10 minutes.
Add the water and vinegar, then turn the heat to high.
When it starts to boil, remove from heat, season with salt and pepper to taste, and set aside.
Combine the Koshary:
Pour the olive oil into a heavy-bottomed 12-inch stainless steel skillet set over medium-high heat.
When shimmering, add all of the ingredients except the fried onions.
Sauté, stirring frequently, until heated through.
Now assemble the dish:
Scoop the rice mixture on a plate or bowl.
Top with the tomato sauce and garnish with the french-fried onions.
