I love fruit and veg.
Here are two ideas.
Stuffed Portabello mushrooms. Straightforward, not too fiddly or time-consuming, not expensive, tasty, healthy, so ticks every box. Adapted a bit from this: www.bbcgoodfood.com/recipes/feta-stuffed-mushrooms-mustard-slaw.
Stalks should be removed and added to stuffing mix. Place mushroom caps on baking tray, oiled, brush/pour a little oil on caps, bake in hot oven for a few minutes. Recipe said gills down, I didn’t notice, didn’t matter.
Stuffing –for five caps, I used about 100g Feta, mashed up with a fork, quite a lot of chopped parsley (at least 2 tbs), 2-3 cloves garlic, chopped fine, several walnut halves roughly chopped, the mushroom stalks, also roughly chopped, salt, pepper, some burghul. The recipe said to boil the burghul for 8 minutes. Didn't need quite as long as that. Burghul could easily be replaced by wholemeal breadcrumbs or cooked rice. Mix all ingredients together, spread over mushroom caps (gill side up), bake for 10-15 minutes until heated through and lightly coloured on top.
I served them with stuffed peppers. The peppers (any colour, or a mixture of colours) were stuffed with an improvised mixture of cooked brown rice, fried spring onions, garlic, cinnamon and pine nuts, currants, parsley, lemon juice. The peppers were placed in a casserole where I had a thick tomato sauce (red onions, garlic, tomatoes, oil, salt, pepper, oregano, basil) and to which I had added sliced runner beans (raw). Casserole in oven for at least half an hour. Worked very well.
