Step 1
Cube potatoes into 1-inch pieces (leave skin on). Slice bell pepper into 1-inch strips. Pat tuna dry.
Step 2
Heat 2 tbsp olive oil in a large pot over medium-high heat until it shimmers, ~90 seconds.
Step 3
Sear tuna 2 minutes per side without moving — surface should look caramelized, inside still rare. Remove to a plate.
Step 4
Add potatoes and peppers to the same pot, stir 2 minutes until peppers soften slightly, then add minced garlic (1 clove).
Step 5
Pour in white wine, scrape up any browned bits, then add stock and olives. Simmer 8 minutes until potatoes are just tender.
Step 6
Slide tuna back in, breaking it into large chunks. Simmer 2 more minutes until tuna is cooked through but still juicy.
Step 7
Taste and season with salt and pepper. Ladle into bowls, scatter parsley on top, and serve hot.
