Set the oven in a grill mode at 250 degrees Celsius.
Prepare a deeper oven baking pan with baking paper
Cut all vegetables into 2-3 cm slices (including broccoli stems) and place them into a larger bowl.
Take a smaller bowl to mix the marinade and mix together:
olive oil
apple cider vinegar
all spices + salt
crushed garlic
Pour the marinade into the vegetable bowl and mix thoroughly. Use your hands to make sure all the broccoli bouquets are covered and make sure that the zucchini pieces do not stick to each other.
Pour the vegetables onto the baking pan and distribute them evenly.
Put the vegetables into the middle part of the oven and start baking.
While the vegetables are in the oven, dice the halloumi cheese into 2-3 cm slices.
Bake until they are half done (starting to become golden brown). Remove the baking pan from the oven and place the diced halloumi cheese evenly over the vegetables. Put the vegetables back into the oven.
Bake until the vegetables are golden brown and feel soft enough.
