Cook mushrooms (sprinkled with salt) in 1 tablespoon olive oil in cast iron skillet on medium-high heat, without moving mushrooms for 4 minutes, to get a nice golden sear. Flip the mushrooms and cook for a couple more minutes. Remove to a plate.
To the same, now empty, skillet add chopped bell peppers, another tablespoon of olive oil, and cook bell peppers until just softened, about 5 minutes, on medium-high heat. Remove from skillet.
Add ground beef to the same, now empty, skillet, and cook, crumbling it, and frequently stirring, until cooked through. Once the beef is completely cooked, drain any liquid and fat.
Make sauce
While you cook the veggies and the beef, combine all sauce ingredients in a small bowl.
Assembly
Return cooked bell peppers to the skillet with cooked ground beef. Add the sauce. Reheat on medium heat and mix to combine. Add cooked mushrooms and chopped green onions. Continue stirring so everything is nicely coated.
Taste and if it's not seasoned enough, add another tablespoon of tamari sauce.
Top with toasted white and black sesame seeds.
Serve as is or over cooked rice (Jasmine or Basmati).
Notes
How to toast sesame seedsI like to use toasted sesame seeds as they acquire a richer, nuttier flavor. Toasting sesame seeds is optional but highly recommended. Here is how to do it - this step can be done when you cook everything else.
Preheat the oven to 350 F. Spread the sesame seeds on a parchment paper-lined baking sheet in one layer.
Bake for about 10 minutes until sesame seeds turn nicely brown, roasted color.
