To a medium saucepan add rice (1.5c), water (3c), and salt (pinch). Bring to a boil. Reduce heat to simmer and cover. Cook for 20-30 minutes, until water is absorbed. Remove from heat and set aside.
Heat a medium skillet over medium heat. Once hot, add 1 Tablespoon sesame oil, chopped spinach (3c), salt (to taste), and sesame seeds (to taste). Saute until tender and dark green. Transfer to a small bowl.
In the same skillet, add another 1 Tablespoon of sesame oil, mushrooms (8oz), salt (to taste), and sesame seeds (to taste). Saute until tender. Transfer to a small bowl.
In the same skillet, add 1 Tablespoon of sesame oil and as many tofu slices as will fit in one layer. Season with salt and pepper, to taste. Cook for 3-5 minutes (until browned), then flip to other side. Cook additional 3-5 minutes (until browned). Repeat process until all tofu slices are cooked.
Combine cucumbers (2), sesame oil (1 Tblsp), and sesame seeds (to taste) in a medium sized bowl. Set aside.
Combine carrots (2), sesame oil (1 Tblsp), and sesame seeds (to taste) in a medium sized bowl. Set aside.
Once all pieces are ready, add rice to bowl, desired vegetables/protein, and optional additions.
I recommend adding a gochujang sauce for extra flavor.
Serve immediately!
