The mayonnaise should be put in a small mixing dish.

Chipotle peppers and garlic should be finely minced before being added to mayonnaise.

Add the salt, pepper, onion powder, molasses, vinegar, and cumin. Discard the aioli.

In a big skillet over medium heat, warm the oil.

When the onions are golden brown, add the peppers and simmer for an additional 15 to 20 minutes, turning periodically. Add salt and pepper to taste.

Put the sandwiches together.

The hoagie rolls should be lightly toasted under a broiler or on a grill.

The tri-tip steak should be cut into thin slices. To obtain tender slices of meat, slice against the grain.

The toasted buns should first have the chipotle aioli spread on them before being topped with the onion and pepper mixture. Two slices of cheese and a mound of tri-tip slices should be placed on top of the onions.
