You can have a supply of salad leaves from your greenhouse from about Christmas on. Once you've cleaned out the tomato and pepper plants, tidy up the soil and rake in a general purpose fertiliser. Sow with any of the many varieties of salad leaves - a good selection in short rows gives you variety and spreads your risks. Most will germinate in a matter of days in the autumn warmth. Start to cut them as soon as they're big enough, they'll keep on growing even in the coldest weather. Come spring, the plants will get too coarse and start to flower; your signal to clean them out and replace the soil ready for next year's tomatoes.
I've tried winter greenhouse lettuce every year as part of my mix, but never had much success. They always get downy mildew. Maybe you'll do better, but I've found the oriental-style mixes give the best results.
