Thinly slice the onion. Coarsely chop the capsicum. Quarter the zucchini lengthwise and thinly slice. Drain and rinse the beans.
Step 2 — Start stew
Heat 1 tbs olive oil in a medium deep frypan over medium-high heat. Cook the onion, capsicum and zucchini, stirring regularly, for 5 mins or until softened. Add the Spanish seasoning and cook, stirring occasionally, for a further 1-2 mins until fragrant.
Step 3 — Simmer stew
Add the tomatoes, 2 tbs water and ½ tsp white vinegar to the vegetables and bring to the boil. Reduce the heat to medium, cover and cook for 6-8 mins until slightly reduced.
Step 4 — Grate parmesan
While the stew is cooking, finely grate the parmesan.
Step 5 — Finish stew
Add the pulled pork and beans to the stew. Cook, stirring regularly, for 2 mins or until heated through.
Step 6 — Get ready to serve
Gently stir the olives and ½ tsp sugar into the stew until combined. Taste, then season with salt and pepper. Divide the stew among bowls. Scatter with the parmesan to serve.
