This Loom walks through making a western omelette, including how to check pan readiness and when to add ingredients. The presenter confirms there is a light coating of oil and tests the pan by sprinkling a drop of water to see it sizzle, noting it usually takes about a minute on medium heat. They pour in whisked eggs, let them cook until small bubbles form around the edges, and then add chopped veggies. Cheese should be sprinkled when the eggs are mostly set but still slightly running, then the omelette is folded and cooked briefly to finish. The video also notes the heat might be slightly high and advises lowering it to avoid overcooking.
