Red (or any) bell peppers, poblano peppers, banana peppers, Padrón peppers, cherry peppers, shishito peppers, habanada peppers, all peppers with no heat.

Furthermore "heat," while commonly conflated with "spice," is not "spice." "Spices" are not necessarily "hot:"

Anise, allspice, cardamom, mustard seed, coriander, dill seed, clove, nutmeg, turmeric, saffron, vanilla, garlic, mace, sweet paprika, fennel, caraway, cumin, sumac, poppy seeds, sesame seeds, and MORE!

are all not-hot spices. You have been riddled.
