Ingredients
- 120g tuna in spring water, drained
- 80g wholemeal bread
- 90g tomato
- 90g spinach
- 40g katsu-style sauce
- 4.6g olive oil
Equipment
- hob
- non-stick frying pan
- knife
- chopping board
- spatula
- kitchen scales
- sandwich toaster or lidded frying pan
- bowl
- plate
Method
- Wash and finely slice the vegetables. Use ready-to-eat cooked fillings and fully cooked canned beans as listed; do not put raw meat into a sandwich toaster.
- Use ready-to-eat tuna in spring water, drained. Drain canned tuna before weighing; keep ready-to-eat fillings refrigerated until needed. Do not start this method with raw meat.
- Mix any cold dressing with the filling; keep excess salad or wet tomato aside to serve alongside. Fill the bread with a manageable amount of the measured filling.
- Toast in a sandwich toaster, or a covered non-stick pan turning carefully, for about5–8 minutes until the bread is crisp and the filling is hot throughout. Cooked-meat fillings must be steaming hot in the centre. Serve all remaining salad/filling alongside and eat immediately.
