Supermarket loaves often contain soya flour. Check the bag.
Yeast extract from brewing carries barley. The maker says it is not suitable for coeliacs.

Flags follow UK labelling rules and come from the ingredients as listed, not from any particular brand. Check the packet before cooking for somebody with an allergy.

Ingredients

Wholemeal bread2 slices, about 80 g
Yeast extract1 tsp, about 6 g
Reduced-fat cheddar30 g
Egg1 large (55 g)
Cider vinegarA splash, for the poaching water
Black pepperTo taste

Method

Bring a pan of water to a bare simmer with a splash of vinegar. Crack the egg into a cup, slide it in and leave it for three minutes.
Toast the bread, spread the yeast extract thinly and grate the cheddar over.
Slide it under a hot grill for a minute until the cheese bubbles.
Lift the egg out onto kitchen paper, set it on the toast and add black pepper.

Worth knowing

Reduced-fat cheddar melts less prettily and has 15 g of fat per 100 g against 35 g for the full-fat block. At 30 g that is 6 g of fat saved on the plate.
A teaspoon of yeast extract is all it takes. Two is salty enough to cover the cheese.
