You can start looking he

Manchego (aged) = queso Manchego viejo Notes: Aged Manchego cheese is
yellow and a terrific grating cheese. Don't confuse it with unaged Manchego
cheese, which is almost white, semi-firm, and typically used as a melting
cheese. Substitutes: pecorino Romano OR other firm cheese OR nutritional
yeast (This substitution works best if recipe calls for cheese to be
sprinkled over a dish. Nutritional yeast is low in fat, high in protein and
B vitamins, and it's not made with any animal products.)

Manchego cheese Notes: Don't confuse this with aged Manchego cheese,
which is firm and yellow, and typically used for grating. Younger Manchego
cheese is sweet and nutty. It melts nicely and is often used in
quesadillas. Substitutes: Monterey jack OR mozzarella OR cheddar

Personally, I would use an Asiago.
