Place the poblano, garlic cloves, cilantro, spinach, bouillon powder, and hot water in a blender. Blend on high until completely smooth.
Measure the total contents of the blender. You should have 1 cup of liquid. If you have more, discard the extra. If you have less, add extra water to bring your total liquid up to 1 cup.
Heat the olive oil in a small stockpot over medium heat
Add the dry rice into the pot with the olive oil. Lightly toast/stir the rice in the oil for 1-2 minutes.
Pour the 1 cup of liquid from the blender into the pot with the rice.
Bring the pot to a boil. Then lower the heat to a simmer and cover.
Cook for approximately 15 minutes, until the water is absorbed and the rice is soft and fluffy.
Remove from heat. Lightly fluff with a fork and serve.
