For the spinach, if you can get chopped, perfect, it just leaf and frozen in balls, you can still use, thaw them out and grab a Chef's knife and chop them, problem solved. Squeeze out the water, and set aside.

In a mixing bowl, add the shrimp, season with a pinch of salt and half the white pepper, mix to coat all the shrimp. Set aside.

Heat some oil in a large pot, add the shrimp and cook, turning them after about two minutes and cook for another 2 minutes, until the shrimp are pink and cooked through, do not overcook them as that makes for tough shrimp. Remove when cooked through.

Same pot, now add the chicken, also just cooking for about 4 minutes, turning them at about 2 minutes, until cooked through, remove the chicken from the pot.

Same pot, heat more oil if needed, add the onion and saute until is translucent then stir in the tomatoes and cook on high heat, covered, for 10 minutes, stir occasionally, after 10 minutes covered, leave pot uncovered and cook for 5 more minutes, also stirring occasionally.

Lower heat to a simmer, add in salt to taste, the chicken stock powder, and spinach and mix well, then add in the shrimp and chicken mix to combine, Allow to heat for just a few minutes to warm the chicken and shrimp through. Remove from heat.

Serve warm with rice, or even pasta.
