7. Stir in the flour very well, then slowly pour in the hot marinade while stirring with a whisk to bind the sauce without lumps.
8. Add the chopped tomatoes, reserved vegetables and aromatics. Bring to a brief boil, then reduce the heat, cover and cook very gently for 1 hour, stirring a few times during cooking.
9. Heat the olive oil in a large non-stick frying pan and sauté the plant-based beef and plant-based bacon pieces (if using) over a medium-high heat, stirring regularly, for 4 minutes.
10. Gently stir this through the sauce, along with the olives, and continue cooking, covered, over a very low heat for a final 15 minutes. Do not stir during the final cooking time.
11. Remove the orange zest and bouquet garni. Taste, and adjust the seasoning if necessary.
12. Serve with mashed or boiled potatoes, polenta or coquillettes (a French type of pasta similar to macaroni), crusty bread and a glass of Côtes du Rhône.
