Preparation and assembly
- Start the main dish and longer roasting first; prepare sides while it cooks. If components need different oven temperatures, cook them sequentially and keep the main covered and warm. Use the quantities listed for each component.
- Mushroom Wellington: Sauté chopped onion in 15 ml oil for 6 minutes. Add finely chopped mushrooms and salt; cook for 12–15 minutes until the pan is almost dry.
- Mushroom Wellington: Drain lentils well. Mash half roughly, then mix with mushrooms, chopped walnuts and breadcrumbs. Cool the filling completely so it does not soften the pastry.
- Mushroom Wellington: Unroll pastry on baking paper. Shape filling into a log, wrap, place seam-side down and cut three steam vents. Brush with soy milk and remaining oil.
- Mushroom Wellington: Bake at 200°C for 35–40 minutes until deep golden. Rest for 10 minutes and slice with a serrated knife.
- Lemony green beans: Trim green beans and boil for 8–10 minutes until tender but not mushy. Drain.
- Lemony green beans: Toss while warm with oil, lemon and salt. For a cold version, first rinse under cold water and dry.
- Mustard vinaigrette: Whisk mustard with vinegar and syrup. Drizzle in oil while whisking.
- Mustard vinaigrette: Transfer to a small leakproof container and shake before using.
- Divide the main dish and sides into equal portions. Serve sauces separately and slice rested dishes only after their stated resting time.
Beginner-friendly tips
Read these three practical tips before cooking. Check how the food looks and feels, not just the clock.
- Preheat the oven fully and spread the pieces in a single layer with gaps. An overcrowded tray steams vegetables instead of roasting them.
- At the end, pierce the thickest piece with a fork: the centre should be tender and the edges lightly browned. If firm, roast a few minutes longer.
- If the top darkens too fast, move the tray down or lower the temperature slightly. If pale, roast uncovered for the final minutes.
Tip
Prepare fillings and sauces first for a calmer lunch. Loaves and layered bakes need resting for neat slices. Time is an estimate for a home kitchen; one oven may require longer.
