In a pan put olive oil and put on stove to get hot. Then you separately fry for 2-3 mins each vegetable separately. Set all side and make sure each has a slight brown shade after being fried. The next step is to layer your moussaka.

To start layering the moussaka take out an oven dish and drizzle a little olive oil at the bottom. You then start with the potatoes. Sprinkle a little bit of salt and put some Thyme leaves evenly throughout

Then you follow the same step in the following order. Potatoes, then zucchini, then onion and lastly the aubergine / egg plant. Make sure there is a little salt and thyme in between each layer.

Cooking the meat: Thinly cut the remaining onion and the garlic. Heat a pan with olive oil and add the onion and garlic and cook for 2-3 mins till slightly brown. Then add the 2 table spoons of tomato paste and cook for 1min while stirring constantly. Then add the mince meat all in. Continue to stir and cook all till brown. Then add a can of diced tomatoes to the meat and now cook them all for another 15 mins stirring slightly now and again.

Now to make the Béchamel sauce: take a 100g butter and add to a pan on stove. Let it melt and add 100g of all-purpose flour. Make sure to constantly stir throughout until this mixture starts to thicken. Now add 750ml milk by adding about 150ml at a time until the 750ml is done. (You add 150ml continue to stir and then as thickens add the next 150ml.) etc
Your béchamel will be ready when small bubbles come up in the surface. When this happens remove pan from heat.

Final layer: now add the remaining béchamel sauce on top and some trimmed cheese to finish.
