Pat the meat dry. Season with roughly ground garlic and dust with cornstarch.
Heat a little oil in a high-sided pan over medium-high heat. Fry the meat for 2-3 minutes until browned on all sides. Season with salt and pepper, then remove to a plate.
In the same pan with the remaining fat, sauté the onion and bell pepper strips over medium heat for 3-4 minutes until starting to soften. Season with salt, pepper, cayenne pepper, and paprika powder.
Add the canned tomatoes, frozen peas, and ajvar. Stir to combine and simmer for 5 minutes.
Return the meat to the pan. Simmer for 3-4 minutes to heat through (pork should reach 63°C / 145°F internally). Taste and adjust seasoning with salt, pepper, paprika, and cayenne as needed. Finish with Maggi or Worcestershire sauce to taste.
