I’m sure everyone else has already noticed this, but in Exodus 29:38ff the twice-daily (morning & evening) lamb offering in the Tabernacle is offered with bread and wine:

A few stray observations, with no particular ordering:

• The “bread” is composed of flour and oil. One might object that as described it is not bread yet but merely a sort of flour-oil paste. However, this is of course a burnt offering: the bread is baked, as it were, in the fire, as it is being offered.
• There is, of course, no leaven in this bread. The Passover (which of course involves the sacrifice of a lamb) is followed by the seven-day Feast of Unleavened Bread, on the first day of which all leaven is cleaned out of every Israelite house. There is no permanent regulation of which I am aware that prescribes leaven the rest of the year. But the collocation of lamb & unleavened bread recalls this festal season. Dare we infer: the Tabernacle exists in a sort of permanent Passover state, or is indeed a kind of permanent Passover?
• The bread and wine are offered with the lamb. They are not substitutable with the lamb, but are its essential accompaniment in sacrifice.
• Similarly, the description of the daily offering as a “sweet savor” comes not in reference to the lamb, but to the lamb with the bread and wine.
• The covenant language of the LORD’s presence with Israel, “meeting” her and “speaking to” her, sanctifying the Tent of Meeting by His presence, dwelling among her and being their God, is not novel to this passage — but its reiteration in connection with the daily sacrifice is, shall we say, suggestive.
• The “grain and wine and oil” of, say, Joel 2, are all present here: the signs, by the fruit of the earth, that the nation is blessed and enjoying abundance.
• To get (potentially) fanciful: Flour symbolically combines various Scriptural images of judgment, death, and resurrection. A kernel of wheat falls to the ground and “dies” so that the plant may “bear much fruit” (John 12). The wheat must be threshed to separate the chaff (which is to be burned unto destruction) from the kernels. The kernels are then ground up to make flour; one thinks of St. Ignatius’ image of himself, preparing for martyrdom, as the “pure wheat of Christ.” Oil, then, is associated with the Spirit; while wine stands everywhere for blood and thus also for judgment.
• More on leaven: In 1 Corinthians 5, when St. Paul is instructing his wayward congregation to expel the man who has his father’s wife (a kind of symbolic, if not necessarily literal, incest), he appeals by analogy to… the sequence of Passover and Feast of Unleavened Bread. “Christ, our Passover lamb, has been sacrificed; therefore let us celebrate the festival, not with the old leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.” In expelling notorious evildoers, the churches honor the once-for-all Passover of Christ by keeping a permanent Festival of Unleavened Bread.
