I'm not sure if it's exactly the one on here but I can share anyway!
Bean sauce
Using fry lite cook off chopped half red onion, whole leek, 2 carrots, BNS (about a cup full chopped), 1 medium courgette, 5 or 6 mushrooms sliced and 2 cloves garlic. Once softened a little add 2 tablespoons tomato purée and stir thro and cook for couple mins. Add in 1 tin baked beans, 1 tin mixed beans in spicy sauce (or another tin baked beans) and tine chopped tomatoes. 1 stock pot ( I use beef) and half pint boiling water. A tsp of dried basil and oregano, some wostershire sauce and salt and pepper. Cook for about 20 mins gently on job until all veggies r soft.
Experimental white sauce - 1 tub quark, 1tub ff cottage cheese 2 eggs all beaten very well together with splash milk. 1 tsp Dijon mustard (1/2 syn) freshly grated nutmeg salt and pepper and 25g finely grated Parmesan ( 1/2 heA) Beat together all ingredients until smooth.
Like I say i have never tried this sauce before it's a combination of many suggestions I got on another site so giving it a go but I will let u know how it goes!!!!
Just layer up bean sauce with lasagne sheets and the white sauce and bake until browned golden on top!
