For a vegan version you could use vegan noodles instead of egg
noodles. The amounts aren't exact, so have fun experimenting with
how many spices you like!
Sautee bell pepper, onion, garlic and chili garlic sauce in
olive oil for a few minutes.
Add pre-cooked noodles and mix well.
Add curry powder and soy sauce.
Enjoy your vegetarian Singapore noodles!
