Heat olive oil in a skillet over medium heat. Cook and stir onion and garlic in hot oil until tender, about 5 minutes. Add broccoli, water, quinoa, and chicken bouillon cubes to the onion mixture; bring to a boil stirring to dissolve the bouillon cubes. Place a cover on the skillet, reduce heat to low, and simmer until quinoa is fluffy, 10 to 15 minutes.
Step 2
Stir evaporated milk and flour into the quinoa. Increase heat and bring the mixture to a boil; cook and stir until the mixture thickens, about 5 minutes. Season with salt and pepper to serve.
