Prawns and Vegetables Over Pan-Fried Udon Noodles

Combine soy sauce, water, brown sugar, and ginger in a small saucepan over low heat. Simmer sauce, stirring occasionally, until ready to use.

While sauce simmers, combine 1/2 cup water, celery, and bell peppers in another small saucepan over medium heat. Cover and cook without stirring for about 10 minutes. Drain and keep covered.

Combine remaining 1 cup water and udon noodles in a large saucepan over medium heat. Cook for 4 to 5 minutes. Drain noodles and return to the saucepan over medium heat. Stir 1/3 of the sauce into the noodles; cook until heated through, 3 to 4 minutes more. Move noodles to the side of the saucepan and add prawns. Cook until opaque throughout, 3 to 5 minutes.

Divide noodles evenly between 2 bowls. Sprinkle prawns with lemon juice while still in the saucepan and stir to coat. Divide vegetables evenly on top of the noodles; divide prawns on top of vegetables. Spoon remaining sauce on top to taste.
