The prep consists of mixing the ingredients, and layering it with the lasagna sheets.
Basically you mix 50/50 of pre-cut spinnach from a jar, I use the small jars, and premade spaghetti sauce, add about the same amount of cheese as you've added spinnach. I use shredded gouda but I'm sure whatever mildish cheese you can get locally would work. Mix in cream cheese with herbs and two or three heaping teaspoons of pesto. Then you layer this sauce alternating with the lasagna sheets. No need to pre-soak the lasagna sheets, but make very sure they are covered all around with sauce or you end up with hard bits. Bang in the oven at 190c for 40ish minutes.
You'll have to adapt the recipe to what you can find locally, but as most of it's is pre-made stuff from jars there's very little prep. If you want to get fancier about it you can of course substitute jars for hand-cut ingredients instead. In my experience the most crucial ingredient is the pesto. Too much and it's overpowering, too little and the lasagna turns out bland. The rest of the ingredients are quite unspecific in how much exactly you use. I don't measure anything really when making this.
Gotcha. That makes sense. All of the jars sounds like NL where I live, also the Gouda.
I guess when I was picturing a vegetable lasagna, pesto and spinach were not high on my list as I don’t particular care for either of those ingredients.
I have an idea for how to do something similar though with different ingredients! Thanks for writing it all out.
re: spinnach: I'm sure you could substitute it with just about anything really. You barely even taste it in the finished product. It mostly provides bulk and texture.
Yea, for me it's largely the texture that I find so abhorrent! Since I have your attention, are there any products that you find are better in a jar as compared to fresh or in a can? I come from the US and while I would say we also have a wide variety of items in jars, daily staples I would say less so, but we use a lot more cans.
I've been here 1.5 years but I must confess I have little desire to experiment with jars because getting rid of them is a pain in butt given where I live. If the product is superior though, I can make the effort to dispose of the glass appropriately.
