Combine the rice vinegar, sugar, and salt in a small pot. Heat over medium heat until the brine reaches a boil. Whisk to make sure the sugar dissolves thoroughly. Once done, transfer the pickling liquid to a tupperware container or a medium-sized bowl to cool.

Once the pickling liquid is mostly cooled (it’s fine if it’s lukewarm), transfer 1 tablespoon of the brine to the bowl of cucumber. And transfer another 1 tablespoon of the brine to the tomato. Mix well separately. Add the rest of the brine to the carrot. Let marinate for 20 minutes while preparing the rest of the ingredients.

Once done, drain the marinating liquid from the carrots.

Heat 1/2 tablespoon of the peanut oil in a medium-sized pan over medium-high heat until hot. Add half of the garlic and stir a few times to release the fragrance. Add the summer squash. Stir a few times to coat well with the oil. Add 1/4 teaspoon teaspoon of salt. Stir until softened. Drizzle with 1/2 teaspoon sesame oil. Mix well and transfer to a plate to cool.

Cook the spinach the same way you made the summer squash.

Fry the eggs until sunny side up or over easy, according to your preference.

Combine all the sauce ingredients in a small bowl and stir to mix well. (*Footnote 2)

Divide the rice into four serving bowls. Add the vegetables, edamame, and an egg on top of each bowl. Add a spoonful of sauce and garnish with seaweed and sesame seeds. Serve with soy sauce or salt, and extra sauce on the side, in case you need to adjust the seasoning.

To eat, mix everything together and enjoy.
