Heat the sesame oil in a skillet over medium heat. Add the onion, whites of the green onion, garlic, serrano, broccolini and ginger powder. Cook down, stirring frequently, for 5 minutes.
Pour in the cooked lentils and soyaki sauce. Cook for another 5 minutes, or until the lentils are heated through and the veggies have absorbed some of the sauce.
To serve, add rice to each bowl and top with the lentils/veggies, remaining green onion and sesame seeds.

Notes
I get my Soyaki sauce at Trader Joe's.
Be sure to discard any tough ends of the broccolini.
