Season the sliced venison with salt and pepper.
In a large frying pan or large wok, heat 3 tablespoons of oil over high heat.
Brown with meat quickly, 2-3 minutes at most. Cook in batches if you don't have a large enough pan. Remove the meat and set aside.
Add the par-boiled and dried potatoes to the pan and cook while stirring for around 3 minutes. Check to see if one of the cubes is cooked thoroughly. If it's still a little hard, cook for another minute or 2 adding more cooking oil if needed. Remove and set the potatoes to the side.
Discard the cooking oil that's left in the pan. Add the remaining 3 tablespoons of oil and heat over medium high heat.
Add the bell peppers and onions, cook while stirring for about 2 minutes.
Add the sauce, potatoes, tomatoes, and venison to the pan and stir until everything is mixed and coated with the sauce. Cook over medium-high heat until everything is evenly coated and heated through, about 30 seconds
Serve immediately with rice or noodles. Top with fresh cilantro, green onions, and sesame seeds.
