Irish Stew packed with pearl barley is very tasty and feeds us 5 for 2 days (I just double up the recipe), and is super cheap.
Another firm favourite is Sausage and Fennel Ragu...packed with veg, absolutely delicious: (Lidl prices)
Pack of 8 cheapy sausages - £2
Two carrots - 10p
Pack Spring onions - 39p
250g bag sliced mushrooms - £1 (buy whole if preferred but only saves about 10p)
Couple teaspoons Fennel Seeds - 20p
Couple teaspoons lazy garlic - 10p
Teaspoon oregano - 10p
Tin chopped toms - 35p
3 packs of ping rice - £1.05 (use pasta if preferred, even cheaper)
Total - £5.29
Grate carrots, finely chop onions, finely chop mushrooms, and fry gently with fennel seeds, oregano, garlic and a good pinch of salt for 5 mins. Squeeze sausages out of skins, break into chunks and add to pan until browned. Tip in tinned toms, add third of a tin of water if it looks too claggy, and if you want, a big squeeze of ketchup. Cover and simmer for 20mins. Season to taste. Serve over ping rice, nachos or pasta. £1 per person and absolutely delicious. Use a big pot, double up and freeze for another meal the following week.
Also, I make a quiche a week, pastry from scratch is pence and takes about 2 minutes to make. Use up all the leftovers from the fridge, add a couple of red onions (slow fry with sugar to caramelise first), bake with 2 eggs and a good glug of cream beaten together and poured over, and will last a couple of days for DH and I lunches at home, or as one dinner for all, served with new potatoes and green salad.
