Then add the gochujang and cook for another minute or two on low heat. Add soy sauce and palm sugar and mix well to combine. Check seasoning and adjust accordingly.
Increase the heat to high and add the onions and mushrooms. Toss well and cook for 30 seconds; then add the cherry tomatoes and zucchini. Cook for a further 30 seconds on high.
Then add the bell peppers and season with salt. Toss through and remove from heat.
Transfer to a bowl and garnish with coriander leaves, almond slivers and sesame seeds.
Add the havarti cubes just before serving.
Notes
How much gochujang to add to your dish should be a personal one. The quantities I have mentioned keeps it medium spicy taking into account my little champ.
